Question

 You are directed to prepare 100 mL of a 500 mEq/L KOH standard. The primary standard used has a concentration of 0.400 Eq/L. When titrating your KOH 
solution, you discover that 4.0 mL of the primary standard reacted exactly with 5.0 mL of the KOH solution. 
 a. What is the actual Eq/L concentration of the KOH solution? 
 b. How many mEq are required to adjust the volume and concentration of the remaining 85 mL of KOH solution to 100 mL of a 500 mEq/L KOH solution? 
c. How many mL of 12 Eq/L KOH stock must be added in order to adjust the
concentration of the KOH standard to 500 mEq/L? ​

Answer 1

Answer:

The solid (solute) used to make the primary standard must be properly dried before being dissolved to form the primary standard s
