Why Is The Project Soap It Up Tested The Ph Levels Of 2 Herbal Soaps

182 Words1 Pages
The project Soap It Up tested the PH levels of 2 herbal soaps and 2 chemical soaps to see if there's a difference in acidity levels for chemical soaps and herbal soaps. This topic intrigued me because I have always wondered if there is a difference in quality for chemical and herbal soaps. The experiment Soap It Up was conducted during the time period of a week at controlled temperatures not causing any manipulation of data. After the experiment was conducted and the averages of the collected data were taken, results showed that herbal soaps have a lower PH in relation to chemical soaps. After doing some research I learned that soaps tend to have a PH range of from 7-10, all the soaps I tested had PH in a healthy range, so I can assume that

The goal of this experiment is to find out what is the identity of the unknown hydrate? To answer this question first, we should know what a hydrate, and how to identify a hydrate using the law of constant proportions. A hydrate is a pure substance because it contains water molecules embedded in its crystal structure that does not vary. By heating the unknown hydrate, we can calculate the mass of the hydrated, and the percentage of water in the hydrate.

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.

Conclusion: Based on the results of molarity from Trials 1, 2, and 3, it is concluded that our experimental for each trial is .410M NaOH, .410M NaOH, and .450M NaOH. The actual molarity of the NaOH concentration used was found to be 1.5M NaOH. The percent error of the results resulted in 72%. The large error may have occurred due to over titration of the NaOH, as the color of the solution in the flask was a darker pink in comparison for the needed faint pink. Discussion of Theory:

These water samples were all taken from the shores of Barker Lake, meaning that they should be similar and they were. Our class data did not seem to be very precise. This is shown in the data in sites 1 and 2 when one group had 9 ppm and another group had 20 ppm. These samples both came from Salt Creek and should have been similar but were not. Another example of class data being inconsistent or imprecise was on site 4 when one group’s results showed 3 ppm and another group’s showing 6.

The high amount of limestone in the creek neutralized the acid rain that was pouring on the creek. This can also make ph scale go into the alkaline side of the ph scale. The ph scale is healthy, because if it was to acidic it will be unhealthy for the fish. These were some of that factors that were in the

Musician and astronomer, William Herschel, changed the way we look at the sky in the 1780’s. In 1781, Herschel went on an adventure to construct a telescope with bigger reflecting mirrors than had ever been used before (Hoskin). He made a telescope that was top of the line for that time. He discovered Uranus, which was the first planet to be discovered in a very long time (Upgren). Many people inspired and aided Herschel’s desire to study astronomy.

How does the amount of baking soda mixed with vinegar affect the volume of gas produced? The rate of reaction is the increase or decrease time taken at which the products are formed or concentration increase or decrease between a reaction of two or more substances. In the reaction, new bonds are formed whilst others have been broken.

 Two of the same types of plants were used, in order for the results to be reliable.  One of the plants was labelled DISTILLED whereas the other was ACIDIC, so the results don’t get mixed.  The DISTILLED plant was used as a controlled variable, where normal spring water was used (pH 7.3)  The ACIDIC plant was the one the experiment had taken place on, this was where lemon water was used (pH 2.0)  Throughout the experiment pictures were taken, so one will be able to notice the colour change on the acidic plants, as it had started to slowly die. With both plants you are able to notice that they had both started to grow flowers, but more the spring watered plant than that on the lemon juice watered one.  The results of the plant growth was recorded to we would be able to notice the amount it had grown, this would be the water compared to lemon juice.

Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.

Introduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4

Introduction The goal of the experiment is to examine how the rate of reaction between Hydrochloric acid and Sodium thiosulphate is affected by altering the concentrations. The concentration of Sodium thiosulfate will be altered by adding deionised water and decreasing the amount of Sodium thiosulphate. Once the Sodium thiosulphate has been tested several times. The effect of concentration on the rate of reaction can be examined in this experiment.

Aim: To find out the relationship between the greater concentration of sodium thiosulfate when mixed with hydrochloric acid and the time it takes for the reaction (the time it takes for the solution to turn cloudy) to take place and to show the effect on the rate of reaction when the concentration of one of the reactants change. Introduction: The theory of this experiment is that sodium thiosulfate and hydrochloric acid reach together to produce sulfur as one of its products. Sulfur is a yellow precipitate so, the solution will turn to yellow color while the reaction is occurring and it will continue until it will slowly turn completely opaque. The reaction of the experiment happens with this formula: “Na2 S2 O3 + HCL =

Introduction The term chromatography actually means colour writing, and signifies a technique by which the substance to be examined is placed in a vertical glass tube containing an adsorbent, the different segments of the substance traveling through the adsorbent at distinctive rates of velocity, according to their degree of attraction to it, and producing bands of colour at different levels of the adsorption column. The substances least absorbed emerge earliest; those more strongly absorbed emerge later. (Wixom et al., 2011) In chromatography of all types, there is a mobile phase and a stationary phase.

Abstract The unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20◦C and 30◦C). With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.
