Chapter 4: Aqueous Reactions

Question 1

hydration

Answer 1

-water molecules break apart

Question 2

dissociation

Answer 2

• breaks apart into ions

- results in electrolyte solution

Question 3

acids

Answer 3

• always produce a H+

- starts with H+ or end with COOH

Question 4

bases

Answer 4

-produces OH-

Question 5

high conductance values in ions

Answer 5

-means that there’s more ions

Question 6

what types of molecules are the most conductive?

Answer 6

ionic compounds

Question 7

what does H2CO3 break up into?

Answer 7

CO2 & H2O

Question 8

what does H2SO3 break up into?

Answer 8

SO2 & H2O

Question 9

what is the molarity equation?

Answer 9

M= mol/L

Question 10

in a dilution, what happens to volume and molarity?

Answer 10

as volume increases, molarity decreases

Question 11
