Question
State your observation of the following case :
When excess sodium hydroxide is added to calcium nitrate solution
Advertisements
Solution
Calcium nitrate solution on reaction with excess of sodium hydroxide produces calcium hydroxide and sodium nitrate. Calcium nitrate reacts with excess of sodium hydroxide to form a white precipitate of calcium hydroxide, which is sparingly soluble, and colourless sodium nitrate.
The reaction is as follows:
Ca(NO3)2 + 2NaOH → Ca(OH)2 + 2NaNO3
