Explain the normal solution of acids and bases
Answers
Normal solution of acids and bases are explained below:
• For acids and bases, normality is to express the concentration of hydronium ions or hydroxide ions in a solution.
• For example, HCl + NaCl --> NaCl + H2O
• In the above equation, the acid reacts with the base to form a salt and water.
• So in this reaction acid gives one H + for every -OH gave by the base.
• One mole of H+ needs one mole of - OH.
• Normality is the molecular weight divided by the equivalent grams.
The normality is equal to the molarity.
Normal solution of acids and bases:
- Normal solution is a method of expressing concentration of a solution.
- Normal solution is a method of expressing concentration of a solution where one normal solution means the solution contains one gram equivalent of a solvent in 1 litre of a solvent.
- In case of an acid or a base solution, the normality is actually the molarity of the solution multiplied by the equivalence of the acid or base. Like, normality of a sodium hydroxide solution is same as its molarity.
- But it’s different in case of sulphuric acid where the normality of a 1 molar solution is 2.
