ph and poh chem quest 49
cids/bases, set up equilibrium expressions using Ka or Kb. Step 4: Perform Calculations Use the formulas: pH = -log [H⁺] pOH = -log [OH⁻] [H⁺] = 10^(-pH) [OH⁻] = 10^(-pOH) For weak acids/bases, solve quadratic equations if necessary. Step 5: Check Consistency and Final Answer Confirm that the ca
