Suppose you have a solution of naoh of unknown concentration. name three

possible substances that could be used as "titrant" solutions to titrate the naoh

solution.

Ok, so the goal of a titration is to figure out the concentration of the NaOH solution by seeing how much acid it takes to neutralize the NaOH solution. NaOH is a base, you want to neutralize it with an acid. The best acids to use would be a strong acid.

Some good choices would be hydrochloric acid, hydrobromic acid, hydroiodic acid, perchloric acid, nitric acid, or sulfuric acid. In reality, though, you could use pretty much any acid you wanted to.

Oh, and you should probably also add an indicator to your solution so that you know when your titration is done. In this case, a good choice would be phenolphthalein because it changes color right about pH of 8.

indium, and thallium have three electrons i think
