Web1 hour ago · Prepare 100.0 mL of 1.0 M NaA solution in a small Erlenmeyer flask. Use a triple-beam balance to weigh out the proper amount of solid NaA. Label this solution \#2 (1.0 M NaA). 3. We want to make 40.0 mL of 0.50MHCl by … WebWe can calculate the pH of the buffer solution that forms when we mix the two solutions together using the Henderson-Hasselbalch equation. In this case, our numerator is our weak base which is ammonia and our denominator is the conjugate acid to ammonia which is the ammonium ion, NH4+. The ammonia solution had a concentration of 0.16 molar, and ...
