Establishing the concentration of a limewater solution

Plan The aim of this experiment is to find the ducking of a experiment of linden weewee base in g dm?3. I am required to design my avow experiment and choose a range of appropriate equipment and apparatus. The exponent depart be supplied to me. I am provided with 250 cm3 of lime pee, which has been made such(prenominal) that it contains approximately 1g dm?3 of calcium hydroxide. Also on hand(predicate) is hydrochloric acid which has a minginess of 2.00 mol dm?3, this concentration is too much though so it is necessary to scale down it. The apparatus, equipment and chemicals that I will exercising are as follows: - 1) pipette 25cm3 2) Volumetric flask 500cm3 3) conelike flask 250cm3 4) Burette 5) neat tile 6) Clamp and stand 7) Indicator (methyl orange) 8) Limewater (250cm3 with 1g dm?3 of calcium hydroxide) 9) Hydrochloric acid- standard solution (conc. 2.00 mol dm?3) 10) Distilled water Slaked lime dissolved in water is called limewater. linden tree + water system ? S laked lime CaO(s) + H2O(l) ? Ca(OH)2(s) Calcium oxide replys violently with water to produce calcium hydroxide (slaked lime) Addition of gain water to Calcium hydroxide produces the saturated aqueous solution know as Limewater. In the experiment it is necessary to react the Hydrochloric acid with the Limewater in govern to establish the concentration of the limewater.

acidulous + Metal Hydroxide ? table salt + Water The equilibrise equation that takes place is: Limewater + Hydrochloric acid ? Calcium chloride + Water + henry Ca(OH)2(aq) + 2HCl ? CaCl2 + 2H2O In order for the experiment to be accurate and secur e it will be necessary to dilute the Hydroch! loric acid significantly. It is in my tactual sensation that a concentration of 0.1mol dm?3 would enable me to strain reliable results. This would require a dilution performer of twenty. I will...
