As soon as you think that the alkali is close to being neutralised, begin adding the acid more slowly (one drop at a time)5. the indicator changes colour when all the alkalis have been neutralised - phenolphthalein is pink in alkalis but colourless in acids , and methyl orange is yellow in alkalis but red in acids.
