Anamika was very happy to see her small house getting cleaned and whitewashed. She observed that the worker dissolved some pale white powdery material into water, left it for some time & applied this white suspension at the wall. At first, the wall looked pale white however after 2-3 days the walls become shiny bright white in colour. How can you describe what she observed through chemical equations?​
