terms

Question 1

dissociation

Answer 1

splitting of a soluble substance in water into ions, which are now free to move about in solution

Question 2

strength

Answer 2

extent to which an acid or base dissociates when dissolved in water

Question 3

strong electrolytes

Answer 3

completely dissociate in solution and contains only ions

Question 4

weak electrolytes

Answer 4

partially dissociate in solution

Question 5

what do electrolytes do?

Answer 5

conduct electricity due to presence of mobile ions that act as charge carriers

Question 6

concentration

Answer 6

amount of substance dissolved in a fixed volume of solution

Question 7

can strength and concentration be changed?

Answer 7

strength CANNOT, but concentration CAN

Question 8

basicity of acids

Answer 8

number of H atoms in a molecule that are able to form H+ ions when it dissociates in water
- monobasic, dibasic or tribasic

Question 9

will all hydrogen atoms in a molecule dissociate in water to form H+ ions?

Answer 9

no

Question 10

is basicity of acid the same as the strength of acid?

Answer 10

no

Question 11

pH

Answer 11

measures concentration of H+ ions in the solution
