    Introduction Over the next few weeks I will be doing several attempts of the same experiment that involves the reaction of sodium thiosulphate and hydrochloric acid, I will be closely watching the reaction and how long in takes for the reactants to react. As yet I have not decided which of the several variables I will be changing. I also aim to take results of the reaction down onto a table, which then will be transferred onto a line graph, which will show us the nature of the reaction. Variables

    Sodium is an element on the periodic table with the chemical symbol as Na. Sodium, discovered by the English Chemist Sir Humphry Davy, is in the Alkali Metals group on the Periodic Table and it is a soft, silver/white color. Sodium, which is found in the Earth's crust, is important to society. Sodium originated from the Arabic word “suda” meaning headache because sodium carbonate was used as a headache remedy. It is also one of the most well-known compounds to ancient people (Newton). It is a component

    Sodium was first discovered and isolated by Sir Humphry Davy in 1807. Sodium is located in column 1 of the periodic table where all other alkali earth metals, which all of them have only 1 electron which it would happily give to another element that wants it so that it could be “happy” this then creates a positively charge atom also known as a cation. You could also find sodium by knowing its electron configuration which is [Ne] 3s1. Sodium physical properties are that it is silver in color and

I began my experiment with .64g of 2-ethyl-1,3-hexanediol. The molecular weight of this compound is 146.2g/mol. It is converted into 2-ethyl-1-hydroxyhexan-3-one. This compounds molecular weight is 144.2g/mol. This gives a theoretical yield of .63 grams. My actual yield was .42 grams. Therefore, my percent yield was 67%

    Science lab report Aim: To find out the effect of concentration on rates of reaction using Sodium Thiosulphate. and Hydrochloric Acid. The purpose of the experiment is to see how different volumes of Hydrochloric Acid affect the rate of reaction. The reaction, which produces solid Sulfur, it will then be followed by measuring the time needed for the reaction to become opaque/cloudy. Hypothesis: I predict that the higher the volume of concentrated Hydrochloric Acid the less time it will take
