Topic 8: Acid and Bases

Question 1

Bronsted Lowry theory

Answer 1

Acids are proton donors, and bases are proton acceptors

Question 2

Amphiprotic

Answer 2

A substance that can either donate or receive a proton

Question 3

Amphoteric

Answer 3

A substance that can act as an acid or a base

Question 4

Alkali

Answer 4

A base which dissolves in water

Question 5

Neutralisation Reaction

Answer 5

A reaction in which an acid and a base react to form salt and water

Question 6

Indicator

Answer 6

Indicators change colour at different PH’s and are useful to determine the equivalence point.

Question 7

PH

Answer 7

PH is the logarithmic scale of hydrogen ion concentration acidic below and basic above 7 and neutral is 7

Question 8

PH meter

Answer 8

An electronic device which measures Ph and is non-destructive (doesn’t change the chemicals)

Question 9

Universal Indicator

Answer 9

Is a mix of lots of different indicators which is green at neutral Ph, blue at basic Ph and red at acidic Ph. Destructive changes the chemicals its placed in.

Question 10

Ionic Product Constant of Water

Answer 10

The hydronium ions multiplied by the hydroxide ions that naturally dissociate in wafter and is equal to 1.00 x 10-14 at 25 degrees
