Question

Need some help with my chemistry work. The topic is acid an based. Thank you in advanced!

The molar concentration of H3O+ in an aqueous solution would be increased by the addition of KOH.

A. True

B. False

In converting from the pH of a solution to the corresponding H3O+ concentration, the following equation should be used.

[H3O+] = 10–pH

A. True

B. False

Consider the following reaction.

This reaction indicates that:

The following is an accurate description of the ionization of HBr in water.

A. True

B. False

6. If you dissolve 0.10 mol of a generic acid HA in 1.0 L of solution, the pH is 3.5. Is HA a strong or weak acid? Explain your answer.

is a weak base.

is a strong base.

is a weak acid.

is a strong acid.

1) False , because when we add KOH in the solution then it releases OH- ions which will react/combine with the H+ ions of H3O+ and hence form H2O.

so the amount of H+ ions decreases hence the molar concentration of H+ ions will also decreases.
