Question

write a balanced net ionic equation for the following reactions; a)Stontium hydroxide reacts with aluminum nitrate b) nitric acid reacts with ammonia c)Stontium reacts with nitric acid d)Stontium hydroxide reacts with acetic acid

Answer 1

Net ionic equations:

a)Stontium hydroxide reacts with aluminum nitrate

Reaction:;

Sr(OH) + Al(NO3)3 --> Al(OH)3 + Sr(NO3)

Balance it

3Sr(OH) + Al(NO3)3 --> Al(OH)3 + 3Sr(NO3)

Take out spectator ions (Sr and NO3)

3OH-(aq) + Al+3(aq) ---> Al(OH)3(s)

b)

nitric acid reacts with ammonia

NH3(aq) + HNO3(aq) ----> NH4NO3(aq)

The net ionic (take out espectator ions)

NH3(aq) + H+(aq) + ---> NH4+(aq)

c)

Stontium reacts with nitric acid

Sr(s) + 2HNO3 --> Sr(aq) + H2(g) + NO3-

the net ionic

Sr(s) + 2H+ --> Sr(aq) + H2(g)

d)Stontium hydroxide reacts with acetic acid

Sr(OH)2 + 2HAc --> 2H2O + SrAc

then

2H+(aq) + 2OH-(Aq) --> 2H2O(l)
