Lime water is not white in colour then also it is used in white wash. Give reason |
| Answer» The solution used for white washing of the wall is quick lime(CaO).And when this quick lime is mixed with water it gets converted into slaked lime [Ca(OH)2]and on exposure to the air it finally gets converted into Calcium carbonate[CaCO3] due to which walls shine...1.CaO + H2O -----> Ca(OH)22.Ca(OH)2 + CO2 -----> CaCO3 | |
