A SMALL PIECE OF CALCIUM METAL IS PUT INTO A SMALL TROUGH CONTAINING WATER.THERE IS EFFERVESCENCE AND WHITE TURBIDITY IS FORMED: WRITE AN EQUATION FOR THE REACTION?
Hi Rishav,
When a small piece of sodium metal is put into a trough containing water, then it reacts with water to produce calcium hydroxide along with the evolution of hydrogen gas. The following reaction takes place.
Ca + 2H2O→ Ca(OH)2 + H2
Hope, this answers your question.
Best wishes!
