Acids And Bases

Question 1

Equations for strong acids

Answer 1

Question 2

Weak acids equations

Answer 2

Question 3

Water/Strong Base equations

Answer 3

Question 4

Strong acid

Answer 4

Fully dissociates in an aqueous solution

Question 5

weak acids

Answer 5

Slightly dissociates in an aqueous solution

Question 6

Water equation

Answer 6

H20 <—> OH- + H+
Slightly dissociates

Question 7

Describe neutral

Answer 7

[OH-]=[H+]

Question 8

Water is endo/exothermic

Answer 8

Endothermic

Question 9

Calculating mixture of strong acid and base steps

Answer 9

Question 10

Different types of indicators and which reactions to use them in

Answer 10

Question 11

Buffer solution definition

Answer 11

Maintains an approximately constant pH
Despite dilution/addition of small amounts of acid/base

Question 12

Acidic buffer solution how formed

Answer 12

1. Mixture of weak acid and one of its salts
2. Excess mixture of weak acid and strong base

Question 13

Basic buffer solution and how formed

Answer 13

1. Mixture of weak base and one of its salts
2. Excess of weak base and strong acid

Question 14

How does adding another acid to acid buffer affect the solution

Answer 14

[H+] concentration increases so reaction shifts to the left to increase the weak acid

Question 15

How does adding acid to base buffer affect solution

Answer 15

H+ reacts with OH- this means that the OH- is decreasing so reaction shifts to the right to make more of the salt
