Mastering Acid Base Titration Your Comprehensive Worksheet Answer Key Titration calculations strong acid strong base calculations (1) use balanced equation to do stoichiometric calculation. (2) determine ph from amount of strong acid base that is in excess. note: at stoichiometry point of equal acid and base, ph =7. example: what is ph after 0.0 ml, 10.0ml, at equivalence point, and 50.0 ml of base has been. Et 15 acids & base equilibria: acid–base titrations objectivesto be able to calculate the ph, poh, and concentrations. ies present at any point of an acid–base titration.vocabularytitrant: the sub. ance whose concentration is known that. is added in a titration. usually the titrant is in the burette.analyt. Answers to the titrations practice worksheet. for questions 1 and 2, the units for your final answer should be “m”, or “molar”, because you’re trying to find the molarity of the acid or base solution. to solve these problems, use m1v1 = m2v2. 1) 0.043 m hcl. 2) 0.0036 m naoh. for problem 3, you need to divide your final answer by two. This document discusses the calculations involved in strong acid strong base and weak acid strong base titrations. it provides an example titration calculation for 0.12m hcl with 0.15m naoh at various base addition points. for the weak acid strong base example, it calculates the ph at different addition points for the titration of 0.12m hf with 0.15m naoh using ice tables and equilibrium.

Ph is defined as the negative log of the hydronium concentration, i.e. ph = log [h 3 o ]. all of the calculations given below reflect this basic idea. values of ph less than seven indicate acidic conditions, while ph values greater than seven indicate basic conditions; a ph reading of 7 is neutral (neither acidic nor basic). Step 1: work out amount, in mol, of sodium hydroxide amount = conc x vol = 0.10 x 0.025 = 0. 00250 mol. step 2: use balanced equation to give moles of ch3co2h. 1 moles naoh : 1 moles ch3co2h so 0.00250 naoh : 0.00250 moles ch3co2h. step 3 work out concentration of diluted ch3co2h in 23.1 (and 250 cm3)in moldm 3.
