Chemistry

Calculate the pH of each of the solutions and the change in pHto 0.01 pH units caused by adding 10.0 mL of 2.67-M HCl to 540. mLof each of the following solutions. Change is defined as finalminus initial, so if the pH drops upon mixing the change isnegative. a) water pH before mixing = Correct: Your answer iscorrect. pH after mixing= pH change = b) 0.153 M C2H3O21- pH beforemixing = pH after mixing= pH change = c) 0.153 M HC2H3O2 pH beforemixing = pH after mixing= pH change = d) a buffer solution that is0.153 M in each C2H3O21- and HC2H3O2 pH before mixing = pH aftermixing= pH change =

Moles of HCL added in each case 0010 L 267 M 00267 moles moles of CH3COO initially present 054 L 0153 M 0083 moles pH of the solution before mixing can be calculated by considering following equilibrium CH3COO H2O CH3COOH OH as CH3COOH is a weak acid so its conjugate base is a strong base and will be completely dissociated moles of CH3COO moles of OH 0153 M pOH See Answer
