Asubstance with a high poh would likely have which of the following? a. a low [h+ ] and a high ph. b. a low [oh– ] and a high ph. c. a high [oh– ] and a low ph. d. a high [h+ ] and a low ph

The correct answer is option(D).

Explanation:

The pOH of the solution is defined as the negative logarithm of the concentration of hydroxide ions in a solution.

From the above relation we can say that:

So, substance with high pOH value will have low hydroxide concentration and lower value of pH.

And lower the pH higher will be the hydrogen ion concentration.

Hence, the correct answer is option(D).

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
