Lesson on Bases and Alkalis

Answer Text:
Bases:
- Are substances which accept the protons donated by acids and are hence proton acceptors.
`NH_3(aq) + H^(+) to NH_4^(+) (aq)`
`CuO(s) +2H^(+) (aq)to Cu^(2+)(aq) +H_2O(l)`
Alkalis:
An alkali is a soluble base i.e. a base that is soluble in water.
- They are compounds, which produce hydroxyl ions in aqueous solutions
`NaOH(aq) to Na^(+)(aq) + OH^(-) (aq)`
Note: -
When an acid proton reacts with a base (hydroxyl ions) in aqueous solution, a neutralization reaction occurs.
