3.3 quiz

Which of the following equations represents the dissociation of a salt?

CaCO3 ==> Ca+2 + CO3-2

Which of the following is CORRECT regarding a H+?

H+ is a proton. H+ is an example of a cation. [H+] in a solution increases when acids dissociate.

The equation H3PO4 + 3NaOH ==> Na3PO4 + H2O represents a neutralization reaction. In this reaction which molecule represents the SALT?

Na3PO4

When NaOH is added to water it dissociates to Na+ and OH- ions. Which of the following is CORRECT about the effect this would have on the solution?

NaOH will act as a base by binding up hydrogen ions.

Which of the following is FALSE regarding the pH Scale?

The larger the pH the larger the [H+] in solution.

Vinegar is a proton donor when added to a solution. This means that vinegar is a(n)

acid and will decrease the pH of the solution.

If you spill HCl on the floor, what should you pour on it to counter the impact of the acid?

baking soda

A buffer

can be both a proton acceptor and a proton donor.

If solution A has a pH of 11 and solution B has a pH of 8, then

solution B has 1000x more H+ than solution A

Based on the following reaction, what best describes the H2SO4 molecule? H2SO4 + H2O ==> H+ + HSO4-

strong acid.
