Question

Discuss how you would prepare 2000 mL of a 0.25 M solution of sodium hydroxide (mass,volume,etc...)

Answer 1

Also: after you make the solution how would you standardize this solution?

Answer 2

find how many moles of sodium hydroxide you need to have that concentration.

Molarity = moles of solute/L of solution

then you can convert that into grams if you'd like.

introduce that into some sort of volumetric or graduated flask and dilute to the volume asked, 2000 mL.

Answer 3

to standardize the solution you would titrate an acid of a known concentration and volume, and ensure that you have however many moles in your standard as you thought.
