acids and alkalis and salts

Question 1

aq is

Answer 1

dissolved in water

Question 2

in aq solutions acids produce

Answer 2

hydrogen ions (h+)

Question 3

HCL (aq)—>

Answer 3

H+ + CL- (shows in aq acids produce h+ ions)

Question 4

bases are usually ___ or ___?

Answer 4

metal oxides or metal hydroxides

Question 5

soluble

Answer 5

able to be dissolved in water

Question 6

bases are chemicals which

Answer 6

can neutralise acids producing a salt and water

bases which are soluble in water are also called alkalis

Question 7

alkalis

Answer 7

bases soluble in water

Question 8

in aq solution alkalis produce

Answer 8

Hydroxide ions (OH-)
eg
NaOH splits to become - Na+ + OH-

Question 9

when we react acid and alkali, what do the ions produce? (the equation for neutralization)

Answer 9

the hydrogen ions react with the hydroxide ions to produce water

H+ + OH- –> H20

Question 10

when we react an acid with either a base or alkali we make a ___ and ___

Answer 10

we make a salt and water

Question 11

acid + metal =

Answer 11

salt + hydrogen

Question 12

acid + metal oxide =

Answer 12

salt + water

Question 13

acid + metal hydroxide =

Answer 13

salt + water

Question 14

acid + metal base =

Answer 14

salt + water

Question 15

acid + metal carbonate =

Answer 15

salt + water + carbon dioxide

Question 16

nitric acid + lithium hydroxide –>?

Answer 16

–> lithium nitrate + water

in alkali lithium hydroxide, the positive ion is the metal lithium. Nitric acid produces nitrates

Question 17

sulfuric acid + zinc oxide –>?

Answer 17

zinc sulfate + water

in base zinc oxide, the positive ion is the metal zinc
sulfuric acid produces sulfates
