Interpretation:
The pH of solution should be calculated. If the solution is acidic, neutral or basic should be indicated.
Concept Introduction:
The concentration of hydrogen ions in a solution determines the acidity of a solution. If concentration of hydrogen ion is more than the solution is more acetic, if it is low, solution is less acidic.
