प्रश्न
One chemical test that would enable you to distinguish between the following pair of chemicals. Describe what happens with each chemical or state 'no visible reaction'.
Calcium nitrate solution and zinc nitrate solution.
उत्तर
Zinc nitrate solution from calcium nitrate solution :
a. \[\ce{ZnNO3 + 2NaOH ->\underset{\text{White gelatinous ppt.}}{Zn(OH)2 + NaNO3}}\]
On further addi tion of NaOH, Zn(OH)2 dissolves.
b. \[\ce{Ca(NO3)2 + 2NaOH ->\underset{\text{White ppt.}}{Ca(OH)2} + 2NaNO3}\]
Ca(OH)2 precipitates are sparingly soluble in excess of sodium hydroxide.
