4 gram of sodium hydroxide was added to20 cc of H2 s o4 solution and the volume was diluted to 1 litre predict whether the dilute solution is acidic basic or neutral and also calculate the resulting normality of dilute solution in terms of gram per litre
Answers
Explanation:
The normality of a solution is the gram equivalent weight of a solute per liter of solution. It may also be called the equivalent concentration. It is indicated using the symbol N, eq/L, or meq/L (= 0.001 N) for units of concentration. For example, the concentration of a hydrochloric acid solution might be expressed as 0.1 N HCl. A gram equivalent weight or equivalent is a measure of the reactive capacity of a given chemical species (ion, molecule, etc.). The equivalent value is determined using the molecular weight and valence of the chemical species.

Normality is the only concentration unit that is reaction dependent.
Here are examples of how to calculate the normality of a solution.
Key Takeaways
Normality is a unit of concentration of a chemical solution expressed as gram equivalent weight of solute per liter of solution. A defined equivalence factor must be used to express concentration.
Common units of normality include N, eq/L, or meq/L.
Normality is the only unit of chemical concentration that depends on the chemical reaction being studied.
Normality is not the most common unit of concentration, nor is its use appropriate for all chemical solutions. Typical situations when you might use normality include acid-base chemistry, redox reactions, or precipitation reactions. For most other situations, molarity or molality are better options for units.
Normality Example:- *1 M sulfuric acid is 1 N for sulfate precipitation since 1 mole of sulfuric acid provides 1 mole of sulfate ions*
