Finding the Concentration of Hydrochloric Acid

Experiment :  To use this standard sodium carbonate solution to find the concentration of (standardise) a given hydrochloric acid solution. Procedure Place 20 ml of 0.0.48 Molar sodium carbonate into a conical flask using a pipette. Add two drops of methyl red indicator. This will give a yellow colour to the solution. Note: the number of drops of indicator… Continue Reading →

Finding Solution of Sodium Hydroxide and Standardising It

Experiment :  To make up an approximate solution of sodium hydroxide and standardise it (find its exact concentration) by titration with the standard hydrochloric acid solution above. Procedure Place 20 ml of the sodium hydroxide in the conical flask. Note: Always place the base in the conical flask as they may react with the ground glass in… Continue Reading →
