A) \[Al{{(OH)}_{3}}\]
B) \[Zn{{(OH)}_{2}}\]
C) \[CaC{{O}_{3}}\]
D) \[Cr{{(OH)}_{3}}\]
Correct Answer: D
Solution :
Here yellow colour is due to the formation of\[Cr{{O}_{4}}^{2-}\]ion. \[Cr{{(OH)}_{3}}+NaOH+N{{a}_{2}}{{O}_{2}}\to N{{a}_{2}}Cr{{O}_{4}}+2{{H}_{2}}O\] Hence, the correct option is (d).You need to login to perform this action.
