Gas evolution occurs between: 1) potassium silicate and hydrochloric acid 2) potassium carbonate and calcium chloride 3) ammonium nitrate and potassium hydroxide 4) zinc nitrate and sodium hydroxide
1) K2SiO3 + 2HCl = 2KCl + H2SiO3 ↓ – (gelatinous precipitation)
2) K2CO3 + CaCl2 = 2KCl + CaCO3 ↓ – (white precipitation)
3) NH4NO3 + KOH = KNO3 + H2O + NH3 ↑ – (ammonia gas evolution)
4) Zn (NO3) 2 + 2NaOH = 2NaNO3 + Zn (OH) 2 ↓ – (white curdled precipitate)
