Total Dissolved Solids Lab Report

388 Words2 Pages

Introductions:
To determine that tap and tank water is potentially healthy drinkable liquids, finding accurate methods that determine which water source is healthier. This EEI will focus on mainly salinity, ph and total dissolved solids (TDS) levels, which are required to experiment on, to determine suitable levels of each water contaminant to find which water is more drinkable, tap or tank water.
• Salinity:
The salinity is the measure of salts in water. Measuring the salt in water ways is important, so that it can be controlled and managed. Salt or sodium chloride can affect the taste, due to the sodium and chloride levels found within the water. High levels of sodium are mostly the problem for high or low amounts of salt. High levels of chloride can cause bacteria growth polluting water ways with parasites.
• Ph: …show more content…

A substance that is less than 7 is acidic and a substance more than 7 is alkaline. The ph level 7 is neutral because the concentration of H3O is the same as pure water. The importance of ph levels is important because it helps scientist determine the solubility; the amount able to dissolve in water.
• Total dissolved solids (TDS):
Total dissolved solids consist of inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulphates) and some small amounts of organic matter that are dissolved in water. http://www.water-research.net/index.php/water-treatment/tools/total-dissolved-solids

Alka Seltzer Dissolve Lab Report

1721 Words | 7 Pages

Problem: How does the temperature of water used to dissolve an Alka-Seltzer tablet affect the amount of time it would take for the tablet to completely dissolve? An Alka-Seltzer tablet is a medicine tablet made with baking soda used as a pain reliever for “headaches, body aches, pain, heartburn, acid indigestion, and sour stomach” (Alka-Seltzer Tablets). It is put into water, left to dissolve and then consumed. When an Alka-Seltzer tablet is dropped into h20, a chemical reaction immediately takes place and produces bubbles made out of carbon dioxide as a product of the collision (Olson 2). When in its original powder (dry) form, the Alka-Seltzer’s two main ingredients: citric acid and sodium bicarbonate are just there and not reacting to each

Lab Report Chemistry Lab

The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

I organized four different tests; pH paper, alkalinity tests, the number of rocks neutralizing acid, and the number of rocks that don’t neutralize acid. The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.

Explain How To Find The Percentage Composition Of Hydrates Lab Report

1573 Words | 7 Pages

Percentage Composition of Hydrates The Introduction: Hydrates are ionic compounds and are often a type of salt with a definite amount of water as part of their structure. Hydrates are decomposed into anhydrous salt, a no-water compound, and water vapor when heat is applied; water vapor is released from the hydrated compound, which leaves with an anhydrous salt that weighs less than the hydrate. But how do we find the percent of the water that was lost after applying heat to the hydrates and how accurate is finding the percent composition of water using experimentation and a gram weight scale? The purpose of the experiment is to find the percent of water lost by finding the difference between the mass of hydrate and the mass of anhydrous

A very low ph level causes the release of metals from rocks or sediments. This can then affect fish and their fry. Throughout the test for total dissolved solids things like residential runoff, discharges from industrial sewage treatment plants, and minerals are detected. Water is a powerful solvent, and can easily pick up impurities. High total dissolved solids alter taste and quality of water.

These facts introduce and support the message that Standage is delivering. Standage continues with many statistics: “Admittedly, both kinds of water suffer from occasional contamination problems but tap water is more stringently monitored and tightly regulated than bottled water. New york city tap water, for example, was tested 430,600 times during 2004 alone.” He stated. Even though he admits that both of each kind contains chemicals-which at the same time Standage claims that the tap water is more sanitized-but also he points out that it is not the taste that differs between the two

Lab 2 – Water Quality and Contamination Experiment 1: Drinking Water Quality Bottled water is a billion dollar industry in the United States. Still, few people know the health benefits, if any, that come from drinking bottled water as opposed to tap water. This experiment will look at the levels of a variety of different chemical compounds in both tap and bottled water to determine if there are health benefits in drinking bottled water.

Dissolved Oxygen Saturation Lab Report

797 Words | 4 Pages

An experiment was conducted to determine the dissolved oxygen, phosphate and nitrate in Freshwater Creek on 22nd February 2016 at 10:46 am. The same tests were done by students previously however in this report only the recent 2 years results will be taken into consideration for comparing trends, anomalies and interrelationships. The recommended levels of dissolved oxygen saturation is 85%. The dissolved oxygen saturation last year was 85% at water temperature 22.9° and 2 years ago being 92% at water temperature being 23.1°. However this years it was recorded to be 80% at water temperature of 27.2° (see appendix 1 for the raw data table and calculations of Dissolved Oxygen).

The Chemistry Of Natural Waters Lab Report

Numerous tests have been created to measure the magnitude of said concentrations. The tests range from simply evaporating the solvent and examining the leftover nonvolatile residue that remains, which is known as the total dissolved solids (TDS) of the sample, to chemical titrations using indicators (EDTA), to advanced spectroscopy of the sample using emission spectrums to determine ion absorbance values (AA Spectroscopy). There are a few differences between AA Spectroscopy and EDTA titrations when it comes to determining water hardness as both tests use different techniques. AA Spectroscopy is used to determine the concentration of metal ions in a water sample.

Why Is Bottled Water Better Than Tap Water

524 Words | 3 Pages

It is important to question the water that we drink for the evaluation of our safety and health. Our sources for suitable drinking water is divided between bottled water and tap water. Tap water usually has a bad reputation when it comes to the "cleanliness" or the "purity" of the water. Bottled water usually has the good image between the two where people think it's cleaner and safer than tap water. In actuality, both sources of water have their own pros and cons, it is just a matter of preferences on risks and benefits that needs to be considered.
