The reaction of the strong acid HCl with the weak base CH_3NH_2 is: HCl(aq) + CH_3NH_2(aq) rightarrow CH_3NH_3^+ (aq) + Cl^- (aq) To compute the pH of the resulting solution if 15mL of 0.31 M acid is mixed with 58mL of 0.90M base we need to start with the stoichiometry. Let's do the stoich in steps: How many moles of acid? How many moles of base? What is the limiting reactant? How many moles of the excess reagent after reaction?...

M Review | Constants | Periodic Table - Part A When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A) is represented as What is the pH of a buffer prepared by adding 0.405 mol of the weak acid...

Question two
A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 ml solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O2. The initial concentration of both the acid and the base are 0.0100 mol/0.1000...
