The student repeated the investigation.
The student used solutions that had different concentrations from the first
investigation
The student found that 15.5 cm of 0.500 mol/dm dilute sulfuric acid completely
reacted with 25.0 cmn of potassium hydroxide solution.
The equation for the reaction is:
2KOH + H2SO. - K SO4 + 2H2O
Calculate the concentration of the potassium hydroxide solution in mol/dmand in
gidimº
