5.6 3 Reactions of acids

Question 1

all

Answer 1

salt form

Question 2

acids with metals

Answer 2

salt and hydrogen
metals must be reactive enough
solution is salt is soluble
neutralisation as h+ ions removed from solution
redox transfer of electrons from metals to the h+ ions

Question 3

acids with metal oxides and insoluble metal hydroxides

Answer 3

metal oxide +acid=salt +water
metal hydroxide +acid=salt+water
reactivity doesn’t matter as it is the prescence of metal ions
observation likely the formation of solution
neuralsation h+ ions react with 02- or OH-
not redox no change in oxidation numbers of any of the species

Question 4

acids with alkalis

Answer 4

metal hydroxide +acids =salt+water
titration
no visible changes
thermometer temp raised can be noted
ionc is H+ + OH-=H2O IN AQ
Neutralisation H+ react with OH- ions
not redox no change in oxidation numbers

Question 5

acids with carbonates

Answer 5

metal carbonate +acid=salt +water +carbon dioxide
if salt formed soluble than solution forms
neutralisation h+ react with CO32-
NOT REDOX

Question 6

Hydrogencarbonates

Answer 6

react same way as carbonates of HC03-

Question 7

Test for carbonate of hydrogen carbonate ions

Answer 7

add aqueous acid and test gas given off with limewater
