Chemistry Semester 2 Quiz 2.1.6 Acid and Base Equilibrium

What kind of solution would have a Kb value that is much greater than 1?

A strongly basic solution.

What is an acid?

A substance that increases the concentration of H+ ions when dissolved.

What is a base?

A substance that increases the concentration of OH- ions in solution.

What is always true of a weak acid?

It only partially dissociates in solution.

What is Kb for C5H5N(aq) + H2O(l) C5H5NH+(aq) + OH-(aq)?

Kb=c5h5nh+oh- / c5h5n

Which of the following is a strong base?

NaOH (sodium hydroxide)

Which of the following is a strong acid?

HCl (Hydrochloric Acid)

What is always true of a strong base?

None of the original base remains in solution.

What would happen to a weak base dissociation equilibrium if more products were added?

The concentration of products would increase. (Wrong, will update when I get the correct answer)

What is Ka for H3PO4(aq) H+(aq) + H2PO4-(aq)?

ka = [H+][H2PO4-] /[H3PO4]
