Where (1) refer to the concentrated solution and (2) refer to the diluted solution. To find the normality of concentrated solutions (for liquid only) this law must be used:- Or : Q / prepare 2N solution in 250 ml volumetric flask from 5N of HCl stock solution . Q / prepare 500 ml , 5N H2SO4 solution from original concentrated solution. .

Normality : is the number of equivalents of solute dissolved in one liter of solution. The units, therefore are ... for HCl n=1 . n = No of OH groups for bases. for NaOH n=1. n = No of Cation atoms (M+) for salts ... Whenever you need to go from a more concentrated solution [“stock”] to a less concentrated one, you add solvent [usually ...

Gastric juice is a dilute (5% by weight) solution of the strong acid HCl. However, a 35 % by weight solution of HCl is a concentrated solution of a strong acid. Neutralization reactions. Acid + Base = Salt + Water. HCl + NaOH ----- NaCl + H2O. Hydrochloric acid + Sodium hydroxide = Sodium chloride + Water (Table salt) Antacid tablet “ Tums “

Volume of HCl taken = 50 ml. Normality of NaOH = 0.1N. S.No Volume of NaOH added (ml) Observed conductance(mho) Volume of NaOH used for equivalence point = V ml. Applying normality equation . N1V1 = N2V2. N1X 50 =0.1X V. N1 X50 = 0.1XV/50 = N. Strength = Normality X Equivalent weight. Result: Strength of given HCl solution is Xgm/lit. Precautions:

Normality. Concentrated acids and bases have a specific molarity associated with them which is often expressed in terms of wt%. Fill in the table below for the Molarity or wt% of the particular acid or base. Acid and/or Base wt% Molarity (m/L) Density (g/mL) Hydrofluoric 49.0 1.30 Acetic 17.4 1.05 Potassium Hydroxide 45.0 1.44 3.
