150 mL of 0.5 N nitric acid solutions at 25.350C was mixed with 150 mL of 0.5 N sodium hydroxide solutions at the same temp. The final temperature was recorded to be 28.770C. Calculate the heat of neutralization of nitric acid with sodium hydroxide.
(b) Formic acid is stronger than acetic acid due to its chemical composition. Formic acid is an organic acid as well as active acid in an organic acid.
(i) Sodium carbonate :for softening of hard water ,laboratory reagent.
(ii) Sodium hydroxide: in the manufacture of soap, in the purification of bauxite.
(iii) Sodium hydrogen carbonate: as a mild antiseptic, as...
Sodium hydroxide is obtained by electrolysis of an aq.solution of NaCl in castner kellner cell using Mercury cathode and carbon anode .Sodium metal which is discharged at cathode combines with...
Nitric acid is added to decompose NaCN and Na2S
NaCN + HNO3 → NaNO3 + HCN
Na2S + 2HNO3 → 2NaNO3 + H2S
H2S and HCN are gases and are escaped from the...
Balanced chemical equation of the reaction between Sodium hydroxide and Hydrochloric acid is given by:
Acid + base → water + salt
NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)
