A: According to the balanced chemical reaction, one mole of HBr reacts with exactly one mole of NaOH question_answer Q: 17.75 How many moles of sodium acetate must be added to 2.0 L of 0.10 M acetic acid to give a Due to excessive NaOH, there were accuracy issues in the calculation of the concentration was inaccurate. You know the number of moles of NaOH, because it's the same as the number of moles of KHP. Now, that's different than asking about pH values in the solution, since the actual [H3O(1+)] level is affected by the various equilibrium reactions the salt ions nominally present may have undergone. {}Oqq=vq.L, v1? =_Q1{Ox#1#cdw~-g"qy]F$bM@(JzEAtDC:H.,B?k=hV'K"g~F`ZYZ?fq2Vh5?N4pddL{4yQKsf)3^9"N\X$b:4Kna|:4~Ys-ISE appropriate number of significant digits.
