Sodium Sulphate Reaction Lab Report

Explain why the reaction between sodium sulphate and silver nitrate did not occur even though sodium sulphate is insoluble in the most part? The reaction did not occur because the solution was mixed with 0.1M of silver nitrate and 0.1M of silver nitrate is not strong enough for the reaction to occur. If silver nitrate contained more than 0.1 mole, the reaction would have occurred because silver sulphate is insoluble and is a solid. Why is it needed for barium nitrate and ammonium sulphate to dissolve into water separately first before mixing the two together? Water is required for reactants because it forms dissociated ions which then reacts.This reaction can only occur when barium nitrate and ammonium sulphate is in aqueous state and dissolving the reactants into water turns them into aqueous state. …show more content…

After it rains, people have noticed the statue to erode and lose its color slowly and over a period of time. Explain why this happens based off what you’ve learned in this lab? (APP) Marble is essentially limestone which is made up of calcium carbonate (CaCO3). When the marble is in presence of an acid, it reacts to form water, a gas, and a salt. Therefore, the marble erodes when it is exposed to acid rain such as nitric acid. Furthermore, acid rain is only slightly acidic which causes the marble to erode slowly and over extended periods of exposure. Why is it required to mix an acid with baking soda (sodium bicarbonate) when baking? (APP) An acid is essential to mix with baking soda because it creates carbon dioxide which causes the baked goods to rise. Also baking soda needs to neutralize the acid or else the finished baked good will likely have an unpleasant metallic

Pop Rocks and soda have a very interesting chemical reaction with each other. Soda is a very pressurized drink that has carbon dioxide in it. Carbon dioxide is a pressurized chemical. When it is shaken, it fizzes, and causes pressure, and overflows releasing the carbon dioxide. It is similar to the Pop Rocks.

The results do not support the hypothesis that a higher surface area to volume ratio would result in sulphuric acid being diffused into the agar cubes in the shortest amount of time. This is evident in the results as the exact opposite to what was predicted occurred. Instead of the smallest cube with the largest surface area to volume ratio of 1cm3 having the quickest diffusion rate, it conversely took the longest at 0.092 cm3 per second, whilst the 2cm3 cube with 0.0384 cm3 per second took the least amount of time. This directly refutes the hypothesis. There was also no consistent trend evident in the results.

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). https://en.wikipedia.org/wiki/Limestone The material in this statue is light in color and does not give off a smooth shiny finish like the Statue of Gudea. The detail carved into this statue is easy to make and shows me two people that are of average status but

Reaction Action Assignment 1. How does the leavening action of baking soda work? 2. a) When baking soda is used in baking recipes, the ingredients list will include an acidic ingredient so that the baking soda will react. Because the baking soda is a base, when it reacts with an acid, it will produce bubbles of carbon dioxide.

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.

Weathering and erosion are two processes that sort of shape Earth’s ground and rocks. Weathering is either a mechanical or chemical process that breaks down or shapes rocks, while erosion transports the leftovers of weathering, away. Understanding these processes helps us understand the way lakes, rivers, mountains, shorelines, canyons, and all sorts of other things were formed. For example the Grand Canyon was formed by erosion created from the Colorado River. It is very important to understand how these forces occur to understand the subject completely.
