What is a base?
Proton acceptors

How are hydroxides and oxides formed?
When Gp 1 and Gp2 elements react with water and oxygen
3
New cards
Describe hydroxides and oxides?
Strong bases
4
New cards
What is a weak base?
A poor acceptor of protons, only partially dissociates into ions
5
New cards
Give an equation of a weak base
NH3 + H2O ⇌ NH4+ + OH- (OH has low conc. so low pH/more acidic)
6
New cards
What is a strong base
A good acceptor of protons, fully dissociates into ions
7
New cards
Give an equation of a strong base
NaOH → Na+ + OH- (OH has high conc. so high pH/less acidic)
8
New cards
What does it mean if a solution is cocentrated?
Lots of moles in 1dm3
