How do you prepare a normal solution?
- Normal solutions are prepared by dissolving gram equivalent weight of solute making 1 litre of solution. It means, to prepare 1 liter solution, we have to dissolve the solute equal to the equivalent weight of the solute in grams. Equivalent weight of any chemical is calculated by dividing the molecular weight with its valence.
What is normality of a solution?
- 1. Presentation on Normality 2. The strength of solution measured in terms of gram equivalent per litre is called normality. It is denoted by N. A solution having 1 gram equivalent of the dissolved solute in 1 litre of its solution is called normal solution.
How many equivalents are in a normal solution?
- A normal solution contains one equivalent of solute per liter of solution. For acid-base reactions, an equivalent is the amount of a reactant that can produce or consume one mole of hydrogen ions (using the Brønsted-Lowry definition). So, for example, a mole of HCl or NaOH is one equivalent, but a mole of H?SO? or Ca (OH)? is two equivalents.
