In chem, we did a lab involving the creation of salt using an acid and base. The indicator we used was bromothymol blue, which displayed the pH of the neutralized solution(color was blue-green). Anyways, the salt my group produced ended up being stained a blue color(which would indicate a basic solution). We used a burette and added 28mL of 1 M sodium hydroxide to 25mL of 1 M hydrochloric acid. Could less base be used in order to create non-stained pure salt, or could it be an issue with the saturation of the solution after we heated it up?

To use a Indicator to get the salt is not a good idea, because the salt will be every time stained with the colour. Better is to use a pH probe and titrate to pH 7. No colour involved.
