WebFirst, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. Finally, divide the number of moles of acid by the given volume of the acid solution to find the concentration.
WebCa (OH)2 → Ca^2+ + 2OH ^-1. n = 2. Normality = 2 x 1.2M = 2.4N. Normality = 2.4N. WebClarification to conclusion 1: The solution will NOT change color at the exact instant that [OH-] first exceeds [H+], because the pH at this point would only be very slightly above 7 (which is not in the pH range of phenol). A color change will happen when [OH-] ions is about (2*10^-6 M), because this is when pH is at 8.3. The color change marks the end …
