Question #28431

Hydrochloric acid is

an important commercial acid.

Hydrochloric

acid reacts with ammonium hydroxide forming ammonium chloride.

(i)

Write the acid base chemical equation for above reaction.

(ii)

Calculate the amount HCl required in kilograms to react with 25 kg ammonium hydroxide.

(iii)

Calculate the amount of HCl required to obtain 30 kg of ammonium chloride

Answer:

Hydrochloric

acid reacts with ammonium hydroxide forming ammonium chloride:

$$\mathrm{HCl} + \mathrm{NH_4OH} = \mathrm{NH_4C} \mathrm{l} + \mathrm{H_2O}$$

Reagents react in a 1:1 ratio

Based proportion of m (HCl) / M (HCl) = m (NH₄OH) / M (NH₄OH)

2) M (HCl) = 1 + 35.5 = 36.5

M (NH₄OH) = 14 + 5 + 16 = 35

m (HCl) = 36.5 * 25 / 35 = 25.07 kg

Based proportion of m (HCl) / M (HCl) = m (NH₄Cl) / M (NH₄Cl)

3) M (NH₄C l) = 14 + 4 + 35.5 = 53.5

m (HCl) = 36.5 * 30 / 53.5 = 20.46 kg
