How to carry out titrations
Web29 aug. 2024 · Titration is often used to determine the concentration of a solution. In many cases it is not a simple matter to obtain a pure substance, weigh it accurately, and dissolve it in a volumetric flask as was done in Example 1 of Solution Concentrations.NaOH, for example, combines rapidly with H 2 O and CO 2 from the air, and so even a freshly … WebStep 1: Find the number of moles of acid moles of acid = concentration x volume in dm 3 moles of acid = 0.15 x 25/1000 = 3.75 x 10-3 mol Step 2: Deduce the number of moles of alkali added The equation for the reaction shows the mole ratio is 1:1 H Cl (aq) + NaOH (aq) → Na Cl (aq) + H 2 O (l) moles of alkali added = 0.10 x 45/1000 = 4.50 x 10 -3 mol
