Acids And Bases

Question 1

Acid + base = ???
Example of what kind of reaction

Answer 1

Salt and water
Neutralisation reaction because ph ends up closer to 7 than it was before

Question 2

Types of bases and examples

Answer 2

Metal hydroxides - KOH,NaOH,Mg(OH)2
Metal oxides
K20,CuO,NiO
Metal carbonates -K2CO3,CaCO3,MgCO3

Question 3

Metal hydroxides + acid=??

Answer 3

Salt and water
KOH(S)+HCL(aq)—> KCL(aq)+H2O(i)

Question 4

Metal oxides +acid

Answer 4

Salt +water

Question 5

Metal carbonates + acid

Answer 5

Salt +water+ co2

Question 6

Acid + metal =??

Answer 6

Salt and hydrogen gas

Question 7

Bases that are soluble in water

Answer 7

NaOH
NH3

Question 8

Bases insoluble in water

Answer 8

Mg(OH)2
CuO

Question 9

Bases that are soluble in water are called

Answer 9

Alkalis

Question 10

Most hydroxides are

Answer 10

Soluble in water so bases

Question 11

Common acids bases and alkalis

Answer 11

Acids- HCL,H2SO4,HNO3
Bases-zinc hydroxide ,copper oxide
Alkalis-NAOH,KOH,NH3

Question 12

Phosphoric acid

Answer 12

H3PO4

Question 13

When substances dissolve in water they

Answer 13

Split up into ions or dissociate

Question 14

In water Hcl dissociates into

Answer 14

H+ and Cl -

Question 15

What are arrhenuis acids

Answer 15

Any substance that adds h+ ions into water

Question 16

Base

Answer 16

Any substance that adds hydroxide ions OH- to water

Question 17

Problems with the arrhenius model

Answer 17

-Only describes acids and bases in terms of H+ and OH-
But ammonia can react with hcl to form a salt even though it doesnt have an oh- ion

-only describes acids and bases that are in solution

Question 18

Bronsted lowrey acid

Answer 18

Proton donor

Question 19

Bronsted lowrey base

Answer 19

Proton acceptor

Question 20

Weak acid
Strong acid

Answer 20

Only slightly dissociated in water
Fully dissociates in water

Question 21

Strong bases

Answer 21

Fully dissociate in water
Sodium hydroxide
Barium hydroxide
Calcium hydroxide

Question 22

Weak bases

Answer 22

Forms equilibrium with water
Ammonia

Question 23

What ion is created when H+ ION REACTS WITH WATER BECAUSE h+ cant exist on its own

Answer 23

Hydronium or H3O+

Question 24

Water also slightly dissociates into ions forming an —-

Answer 24

Forming an acid base equilibrium

Question 25

Conjugate acid

Answer 25

-when ever a substance acts as a bronsted lowrey base and accepts a proton we call the product it forms its conjugate acid
When NH3 acts as a bronsted lowrey base it forms a bronsted lowrey acid and that acid is called its conjugate acid

Question 26

When 2 acids mixed together the —— acid always acts as the bronsstead lowrey acid

Answer 26

Stronger acid

Question 27

Water is capable of dissociation. Write an equation to show the dissociation of water molecules.

Answer 27

Question 28

Acidity

Answer 28

Concentration of h+ ions

Question 29

Concentration of h+ ions

Answer 29

= moles of h+ ions / volume

Question 30

Log(x)=3
X=?

Answer 30

X=10 to the power of 3

Question 31

PH=?

Answer 31

PH=. -Log [H+]

Question 32

PH of a strong acid

Question 33

Ph of strong acid

Answer 33

Concentration=h+ ions
Ph = -log[H+]

Question 34

Concentration of strong acid

Answer 34

Concen of strong acid = 10-PH
10 TO THE POWER OF -PH

Question 35

Reacting acid with solid base

Answer 35

Ph will increase
Volume stays the same
