Introduction Magnesium sulphate is used for a variety of purposes i.e. bath salt and as a laxative. It is a hydrated salt and is required to be stored in a sealed container to maintain the water. Magnesium sulphate in a solution is sprayed on plants or poured on soil, as magnesium is vital for plant growth and respiration, it forms part of the chlorophyll molecule which is utilised by plants to convert sunlight into energy. This experiment was performed to determine the degree of hydration for a

Introduction By using a spectrophotometer, we were able to measure the absorbance of Copper (II) sulphate with increasing dilutions. From this we were able to create a graph showing the concentration as well as the absorbance. The Beer Lambert Law is the linear relationship between the absorbance and concentration. This has a connection with the light behaviour as well because light behaviour effects the concentration and absorbance. The more concentrated that a solution is, the less light passes

EXPERIMENT 4: QUANTITATIVE DETERMINATION OF SULPHATE BY GRAVIMETRIC ANALYSIS FORMAL REPORT NAME: CHIA KOK SIONG ADMIN NO: 1027325 CLASS: DFST/FT/2B/21 � SYNOPSIS The objective of this experiment is to determine the amount of sulphate by gravimetric analysis. The amount of sulphate is determined quantitatively as barium sulphate, BaSO4, by gravimetric analysis. For the experiment, a dilute solution of barium chloride was slowly added to a hot unknown sulphate solution slightly acidified with concentrated

copper sulphate using colorimetry. In this task the concentration of an unknown sample of copper sulphate using colorimetry was used to find the concentration. In this investigation copper sulphate was used which is CuSO4.5H20 as a formula. To make a standard solution which was 1M, the same clean equipment was used to make up the standard solution as used to make sodium carbonate. However there was one difference and that was that the hot distilled water was used to dissolve the copper sulphate crystals

A study on the effect of iron sulphate concentration on the growth of Triticum aestivum, as measured by shoot length Background: For the plants development to carry out general processes, an example being photosynthesis, required for life. There are different roles which can be changed, altered, removed or added that can affect the plant, an example being an increase temperature, CO2. Iron is a micronutrient like iron, used by plants for plant growth, it's role a key factor in enzyme present and

of my solutes. My decided solutes are sugar, salt and copper sulphate pentahydrate. I decided I would be using 100mL of water as my solvent due to the abundance of solutes available and that fact that 100mL is a nice, easy number to work with. I also spoke to Mrs Rach and she informed me she has a surplus of copper sulphate so I don’t have to be careful with how much I use. She also gave me some measurements on how much copper sulphate should dissolve into 100mL of water at varying degrees. It’s

Task 7:  Titrations: Method: 1. Firstly you need to need to measure accurately 0.50g of your copper sulphate solution into a 100cm³ beaker 2. Then add about 50cm³ of distilled water ensuring you continue to stir until crystals have dissolved. Then transfer the solution into a 100cm³ volumetric flask 3. Next rinse out the beaker with small amounts of distilled water and transfer the washings to the volumetric flask to ensure none of the solution is wasted affecting the end result. 4. Once the beaker

included more in-text citations and references, expanded on experimental errors in more detail and ensured my aim and conclusion is clear. Abstract The purpose of this investigation was to identify the class of immunoglobulins using, sodium dodecyl sulphate (SDS) Polyacrylamide Gel Electrophoresis (PAGE); by making deductions about the structure and molecular organisation of the protein. The experiment was conducted to calculate the unknown molecular mass for reduced and non-reduced immunoglobulin,
