Question

A total of 25.0 mL of 0.150 M potassium hydroxide (KOH) was required to
neutralize 15.0 mL of sulfuric acid (H2SO4) of unknown concentration. What is the
concentration of the sulfuric acid?

Answer 1

Let the concentration of sulphuric acid be 'X'

milliequivalents of acid = milliequivalents of base

milliequivalents = (Normality * volume in milliliters)

Also, Normality = molarity * n-factor

milliequivalents of KOH = (0.150*1 * 25 )
milliequivalentts of \(H_2SO_4\)=(X*2*15)

Answer 2

remember that u will get the concentration in moles per liters
