tion:Stronger acids have the capacity to PRODUCE higher CONCENTRATION hydrogen ions and can be completely ionized in an aqueous solution. Weak acid produces a fewer concentration of hydrogen ions. Let us learn the way to compare the pH of strong acid and weak acid of same concentration solution.Aim:To compare the pH of solutions of strong and weak acids of the same concentration – hydrochloric acid (HCl) and ACETIC acid (CH3COOH).Materials Required:0.1M HCl, 0.01M HCl, 0.001M HCl, 0.0001 M HCl, and 0.00001M HCl test tubes, glass rod, and universal indicator.The PROCEDURE of determining the pH using pH paper:-Take 2-3 drops of solutions of the given concentration on pH paper with the help of glass rod.Observe the change in colour of the pH paperMatch the shade of the pH paper with standard pH indicator chart.Note the approximate pH of the sampleThe procedure of determining the pH using universal indicator:Take dry 5 test tubes and fill 5 mL of each solution of various concentration given using measuring cylinder.Drop 2-3 drops of universal indicator in each test tube using a dropper.Note the change in the colour seen in the test tube.Compare the colour of the solution in the test tube with a standard pH indicator chartnote the pH of the solutionPrecautions to be taken during the experiment:Ensure to handle the test tube carefully.Do not add more indicator.Keep the pH paper clean.Compare the colour of the solution in the test tube and pH paper colour exactly with the standard pH indicator chart.Observation
