The poh of a solution is 6.0. which statement is correct? use mc030-1.jpg and mc030-2.jpg. the ph of the solution is 20.0. the concentration of oh– ions is mc030-3.jpg. the concentration of oh– ions is mc030-4.jpg. the ph of the solution is 8.0.

D) The pH of the solution is 8.0

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
