between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate‚ and record the amount of time taken for the cross to disappear through the solution from the top of the flask. Record this time and repeat this for different concentrations of hydrochloric acid. Fair Test The variables in this test are: The concentration of hydrochloric acid

Main aim of experiment 5 is to use the biuret test to quantify the concentration of the Bovine Serum Albumin (BSA) then constructing a standard curve graph and to use the spectrophotometer to perform an enzyme assay using different concentration of the BSA. Experiment 5 also verifies the Beer-Lambert Law‚ which is the linear relationship between absorbance and concentration of an absorbing species. Absorbance formula is shown in fig. 1.1. However‚ the Beer-Lambert Law is not obeyed at high concentration

Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation‚ Calcium + Hydrochloric Calcium + Carbon

A Tale of 3 Pumpkins … Pumpkin Three: Ribbon by Heather Well we have come to the end of our tale of the three pumpkins. First‚ we met the lovely and vintage Book Page Pumpkin. Then our journey brought us to the glamorous and classy Faux Nailhead Pumpkin and last we meet the sweet and cheery Ribbon Pumpkin. Isn’t she just a little sweetheart?! Believe it or not she proved to be the most difficult pumpkin to make‚ though you’d never know it by her demure personality and the simplicity of her

The aim for this investigation is to investigate the effects of varying the concentration of sodium thiosulfate solution on the rate of the reaction when reacting with dilute hydrochloric acid. It is hypothesized that as the concentration of the sodium thiosulfate solution increases‚ the rate of the reaction will also increase proportionately. Variables The independent variable is concentration. This will be varied by increments of 10mL (10mL to 50mL) and distilled water will be added accordingly

The Red Ribbon - g/ram Sally Mayfield was eighteen years old when she decided to leave town for the first time by herself. She lived in Brentwood‚ the older side of the valley. The trees were a thicker and the sidewalk was lifted and cracked‚ showing signs of decay. Everyone walked on the street‚ where you could always see a group of kids playing games or the neighbors walking their luxury dogs. Things there were simple and traditional; everything

electrically-charged and moves to either a negative or positive electrode. Ions that move to the negative which are called cations are positively charged and Ions that move to the positive which are called anions are negatively charged. They can be divided into acids‚ bases‚ and salts‚ because they all give ions when dissolved in water. Electrolytes are present in the human body‚ and the balance of the electrolytes in our bodies is essential for normal function of our cells and our organs. Electrolytes are important

Aim: To investigate the rate of reaction between Calcium Carbonate and Hydrochloric Acid. Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. In this investigation the substance that is formed is Calcium Chloride‚ Water and Carbon Dioxide. The symbol equation for this is: CaCo3  Ca2+ + Co32- Hcl  H+ + Cl- Add these all together to get CaCO3(s) + 2H+(aq) --> Ca++(aq) + H2O + CO2(g) The rate of
