Question

Metal chloride A is soluble in hot water but insoluble in cold water. Select correct statement about A.

• A. A can give yellow ppt. wth $K_2{CrO}_4$
• B. A can give white ppt with $K_2{SO}_4$
• C. A can give yellow ppt with $KI$
• D. all the above are correct statements

Answer 1

The correct option is D all the above are correct statements

The metal chloride (A) can give yellow ppt. wth $K_2{CrO}_4$
$MC{l}_2+K_{2}Cr{O}_4\to MC{r}_2{O}_4\downarrow \left(yellowppt\right)+2KCl$
The metal chloride (A) can give white ppt with $K_2{SO}_4$
$MC{l}_2+K_{2}S{O}_4\to M{S}_2{O}_4\downarrow \left(whiteppt\right)+2KCl$
The metal chloride (A) can give yellow ppt with $KI$
$MC{l}_2+2KI\to M{I}_2\downarrow \left(yellowppt\right)+2KCl$
