Ответ:

Кальцій гідроксид Са(ОН)2 (гашене вапно) — сіруватий малорозчинний у воді порошок. При змішуванні надлишку гашеного вапна з водою утворюється суспензія — так зване “вапняне молоко”. Після фільтрування вапняного молока отримують прозорий розчин кальцій гідроксиду, який називають вапняною водою.

Вапняну воду використовують у лабораторній практиці для виявлення вуглекислого газу.
