An investigation to show how the rate of reaction 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

Sandeep Voleti- Period 4/5 Honors Chemistry Titration Lab Writeup Introduction Titration is a method‚ which is meant to find the concentration of either an acid or a base by adding a measured amount of it to a known volume and concentration of an acid or base1. Titration starts with a beaker or Erlenmeyer flask containing a very precise volume of the known concentration solution and a small amount of indicator‚ which is put underneath a burette containing the solution with unknown concentration1

Rust is an iron oxide‚ usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy‚ and form under different circumstances.Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide (FeO(OH)‚ Fe(OH)3). Given sufficient time‚ oxygen‚ and water‚ any iron mass will eventually convert entirely to rust and disintegrate. Surface rust is flaky and friable‚
