A small piece of calcium metal is put into a small trough containing water.there is effervescence and white turbidity is formed. What do you observe when a few drops of red litmus is added to to the turbid solution
Solution
Calcium is a metal and when it is added to water, it forms calcium hydroxide and hydrogen gas is evolved which causes effervescence.
Ca(s) + H2O(l) → Ca(OH)2(aq) + H2(g)
Calcium hydroxide, i.e., Ca(OH)2 is a basic solution and basic solution turns red litmus blue.
