Reference no: EM13187933

Consider the exothermic reaction CoCl42?(aq)+6H2O(l)? Co(H2O)62+(aq)+4Cl?(aq), which interconverts the blue CoCl42? ion and the pink Co(H2O)62+ ion. Will the equilibrium concentration of CoCl42? increase or decrease when the following changes occur? Choose a or b for each part.

Part A

HCl is added.

a [CoCl42?] increases

b [CoCl42?] decreases

Part B

Co(NO3)2 is added.

a [CoCl42?] increases

b [CoCl42?] decreases

Part C

The solution is diluted with water.

a [CoCl42?] increases

b [CoCl42?] decreases

Part D

The temperature is increased.

a [CoCl42?] increases

b [CoCl42?] decreases
