उत्तर
Dilute hydrochloric acid cannot be concentrated beyond 22.2% (by weight) by distillation.This is due to the fact that this mixture (77.8% water + 22.2% HCI) boils at a constant temperature of 110°C without any change in concentration. So if its concentration is high it will fall back at a lower concentration.
