A standard CaCO3 solution is prepared by dissolving 0.4193g in enough dilute HCl to effect solution and then diluted to 500ml solution. A 25.00ml aliquot requires 23.62ml EDTA solution for titration. A 25.00ml water sample determined for total hardness, requires 8.45ml of the EDTA solution using Eirochrome Black T indicator. Calculate the total hardness in the water sample expressed in ppm CaCO3.
why is it necessary to test the ph? PROCEDURE To a six inch test tube was added thiamine hydrochloride (0.65 g), followed by water (2mL). The mixture was gently shaken until homogeneous, and then ethanol (7.5 mL)was added. Finally, sodium hydroxide (10%, 1.5 mL) was added and the mixture wasgently stirred to ensure complete mixing.Benzaldehyde (3.8 mL) was then added at room temperature in one portion with gentlestirring. The pH of the resulting reaction mixture was determined and adjusted to >10by dropwise addition of 10% sodium hydroxide.
