Webb18 aug. 2015 · A 100 ml H C l solution has a pH of 3.7. You want the solution to be of pH 4.5. You have a solution of 10 M N a O H. How much N a O H do you need to add to to the 100 m l solution of H C l to get a pH of 4.5? I firstly calculated the concentration H C l in 100 m l solution = 10 − 3.7 = 2.0 × 10 − 5 m o l H C l per 100 m l. WebbClick here👆to get an answer to your question ️ 5. When 1.0 mL of dil.
