Question

what is seminormal and decinormal

Answer 1

Semi Normal Solution : It can be expressed as 1N solution. when 1/2 gram equivalent of the solute is dissolved in 1 litre of the solution it is called as seminormal solution. it is denoted by N/2

Deci normal solution : When one-tenth gram equivalent mass of a substance is present in one litre of its solution then it is called decinormal solution . it is denoted by N/10 solution.

Eg if 4g NaOH is present in 1000 cc(1litre) of its solution , the solution is known as decinormal solution

Answer 2

SEMINORMAL------A solution containing one half of a gram equivalent weight of reagent in 1 L of solution.

DECINORMAL----A solution contain 1/10 (0.1) gm of equivalent weight of solute per litre of a=solution.
