standard and mixed with 50 mls of distilled water in an Erlenmeyer flask.
2. How many grams of KOH are required to make 500 mls of a 3.5 M KOH
solution?
1.
3. Describe the steps to make the solution from question 2.
4. When NaOH is added to distilled water to make the 0.1 M NaOH solution the
solution gets warm. Why?
5. What are the 2 reasons to put distilled water in the volumetric flask first and then
add the neat NaOH standard?
