2
Q

A
an alkali is a species that releases OH- in solution
3

4
Q
what is neutralisation?
A
a neutralisation is when the proton on an acid molecule is replaced by a metal ion (or ammonia), forming a salt and water
5
Q
how do group 2 oxides react with water?
A
XO + H2O => M(OH)2
group 2 oxides are therefore basic as they release OH- ions when dissolved
6
Q
how do group 2 hydroxides react with hydrophobic acid?
A
X(OH)N + 2HCl => MCl2 + 2H2O
