Reactions of acids and bases

Question 1

dissociation

Answer 1

ionic compound seperates into ions in solutions

Question 2

ionisation

Answer 2

when a molecular compound seperates into ions in solutions, ions didn’t previously exist

Question 3

what are the three reactions of acids

Answer 3

1. acid + metal hydroxide 2. acid + metal carbonates/hydrogen carbonates 3. acid + reactive metals

Question 4

acid + metal hydroxide results in

Answer 4

salt + water

Question 5

acid + metal (hydrogen) carbonate results in

Answer 5

carbon dioxide + water + salt

Question 6

what is used to test the presence of carbonate salts

Answer 6

the limewater test

Question 7

limewater test

Answer 7

an acid is added to a solution and will produce CO2 is carbonate is preesent, limewater is added to a solution and if it turns milky white than carbon dioxide is present as the precipitate CaCO3 will form

Question 8

limewater formula

Answer 8

Ca(OH)2
