Question

if the concentration of Cu2+ is .50 M and the concentration of S2- is 40.0M and both solutions will dilute by a factor of 2, write the expression for the reaction quotient,Q for this reaction. if the concentration of Cu2+ is .50 M and the concentration of S2- is 40.0M and both solutions will dilute by a factor of 2, write the expression for the reaction quotient,Q for this reaction. if the concentration of Cu2+ is .50 M and the concentration of S2- is 40.0M and both solutions will dilute by a factor of 2, write the expression for the reaction quotient,Q for this reaction.

Explanation / Answer

Expression of reaction quotient,

Q = [Cu2+][S2-]

    = (0.025)(20)

    = 0.5  

will be Q after dilution by factor of 2.
