Question

You have died the calcum carbonate to the hydrochlorobbed reading. What is the final volume of the reaction s corte con t ent and to 20 mL 25 ml

You have added the calcium carbonate to the hydrochloric acid. It bubbled until the reaction was complete and all the calcium carbonate had reacted. You look at the graduated cylinder to take a reading. What is the final volume of the reaction?

Answer 1

From the diagram it is clear that the level of the reagent in graduated cylinder is 23 mL.

Here each line is 1 mL. Here mentioned that 20 mL and 25 mL. The level of reagent is 3rd line after 20 so 20+3 = 23 mL (or)

The level of the reagent is 2nd line above the 25 so 25-2 = 23 mL ( this is clearly visible)

Hence the final volume of the reaction is 23 mL.

If the initial volume is 0 mL then the volume of the reagent is 23 mL. If the initial volume is not the zero then the volume of reagent is (Final volume - intial volume)
