WebCalculate the pH at these volumes of added base solution: (a) 0.00 mL (b) 12.50 mL (c) 25.00 mL (d) 37.50 mL Solution (a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then WebOne point is earned for starting between pH 12 and 14 and for finishing below pH 2. One point is earned for locating the equivalence point at pH 7 and volume 40.0 mL. One point is earned for the overall shape of the curve.

WebJan 30, 2024 · We know that NaOH is a strong base and H 2 SO 4 is a strong acid. Therefore, we know the pH of the salt will be equal to 7. 4. By plugging the numbers given in the problem into the equation: M1V2 = M2V2 we can solve for M 2. (0.135) (0.025) = M 2 (0.031) M 2 = 0.108 M. Therefore, the molarity of the unknown solution is .108 M. References WebCaustic soda reacts with all the mineral acids to form the corresponding salts. It also reacts with weak-acid gases, such as hydrogen sulfide, sulfur dioxide, and carbon dioxide.Caustic soda reacts with amphoteric metals (Al, Zn, Sn) and their oxides to form complex anions such as AlO2(-), ZnO2(-2), SNO2(-2), and H2 (or H2O with oxides).
