DETERMINATION OF pH
 Experime nt No: …3…
 
• Objective: To find the pH of DilHCl, Dil. NaOH, Dil. Acetic Acid, Lemon Juice, Water and Dil. NaHCO3 solution, using pH paper (or Universal Indicator).
 
• Requirements: strips of pH paper, test tubes, standard pH reference chart, and various samples
 
• Procedure: Take 1 ml of the given sample in a test tube. Dip a piece of pH paper into it. Note the colour change and compare the same with the colour chart given to find the pH of the solution. Record your observations in the table given below. Repeat the experiment with other samples also and record your observations
