Question

what will be the molarity of 6 n in H2 s o4​

Answer 1

Answer:

Normal

A unit of concentration that requires deeper treatment due to its difficulty is

Normality, which is denoted by the letter N and is defined as the number of solute equivalents

per liter of solution

Normality is a unit of concentration that depends on the reaction in which the

solution and requires some definitions:

• Equivalent of an acid: It is the amount of moles of H + provided by one mole of acid

when dissolved in water.

Examples:

1HCl H2O H + + Cl - 1 eq

1H2SO4 H2O 2 H + + SO4 2- 2 eq

1H3PO4 H2O 3 H + + PO4 3- 3 eq

1HNO3 H2O 1 H + + NO3 - 1 eq

HCl water H + + Cl1 mol HCl = 36.5 g = 1 eq

H2SO4 water 2H + + (SO4) -2

1 mol H2SO4 = 98 g = 2 eq

H3PO4 water 3 H + + (PO4) -3

1 mol H3PO4 = 98 g = 3 eq

• Equivalent of a Base: It is the amount of moles of OH - provided by one mole of base.

when dissolved in water.

1 mol NaOH = 1 eq

1 mol Ca (OH) 2 = 2 eq

1 mol Al (OH) 3 = 3 eq

• Equivalent of a Salt: It is the amount of moles of positive charges provided by a mole of

salt by dissolving in water
