1. DATA
3. CONCENTRATIONS OF BEAKERS 2 AND 4 CONCENTRATIONS BEFORE AND AFTER ADDITION OF BASE Using your measured pH values, calculate the concentration of \( \mathrm{H}^{+} \)in beakers 2 and 4 , before and after the addition of \( \mathrm{NaOH} \).
Expert Answer
When pH is given we can calculate the concentration of H+ ion in following way, Concentration of H+ = 10-pH For Beaker #2 : pH before the addition of NaOH was added = 8.69 [H+] Concentration = 10-pH = 10-8.69 = 2.04174 x 10-9 = 2.04 x 10-9 ( rounded
