To determine the concentration of limewater The aim of my experiment is to find the concentration of limewater solution in gdm. To do this, I am required to construct my own experiment and choosing reliable and appropriate apparatus. I will be provided with 250cm of limewater, which contains approximately 1gdm of calcium hydroxide. I also have hydrochloric acid, which has a concentration of 2.00-mol dm , which is too concentrated and will need diluting. Apparatus, equipment and chemicals Pipette 250cm Burette Conical flask 250cm Volumetric flask 250cm Graduated pipette Clamp + stand White tile Indicator (methyl orange) Limewater (250cm with 1gdm of calcium hydroxide) Hydrochloric acid (2.00-mol dm ) Distilled water Squeezing pump Balanced Equation In order to achieve limewater, dissolved slacked lime in water to get a solution of calcium hydroxide (Ca (OH) 2 ) Quicklime + water --------> slaked lime CaO (s) + H2O (l) --------> CaCl2 (aq) + 2H2O (l) In this reaction it shows the calcium oxide reacts with water to produce calcium hydroxide....
