Why should the sodium hydroxide pellets be completely dissolved in the preparation of the NaOH solution?

please explain thouroughly, thanksss in advance!!

  1. It depends upon what you are doing with the NaOH.

  2. well they are supposed to be used for an NaOH titration. but if that doesnt help, than in general why should they be dissolved?

  3. If the solution is to be used for titration and all of the pellets don't dissolve, what does that mean about the titration? For example, if the concn of the NaOH is determined to be 0.1M but then more NaOH dissolves, what does that tell you about the new molarity of the NaOH. And what does it tell you about the titration you've just completed. It's useless
