This is an analitical chemistry question, any help is appreciated:

Imagine that youre at an analytical chemistry lab in which youll take measurements and calculate pH of different solutions. You and your lab partner are assigned 10.00mL of a 0.0500M solution of NaOH. You must measure the pH with the corresponding instrument and and determine the pH with the corresponding equation. You place the 10.00 mL solution in a beaker to measure the pH but your partner accidentally adds water up until the 100ml line. How would this affect the pH of the final solution when compared with the pH of the initial one?
