When an acid solution is titrated with a standardized base solution, separate burets are sometimes used for each solution. which mistake would necessitate emptying and refilling burets, and starting the titration over? a adding distilled water to the titration flask after a solution was measured into it from the buret b overshooting the endpoint c starting with less acid than called for by the procedure d allowing drops of distilled water to stay in the burets while filling them

d) allowing drops of distilled water to stay in the burets while filling them.

Explanation:

Titration is a procedure where we titrated an analyte with a standardized solution and an indicator. For an acid-base titration, knowing the point where the neutralization is completed (pH becomes 7 for a strong acid and base), we can determine the concentration of the analyte.

To do this is necessary to know the concentration and the volume of the standardized solution. So if distilled water is added to the titration flask after a solution was measured, it will not interfere in the study.

By overshooting the endpoint, the titration must be done again, but the volume of the burets only needs to be completed. Same as from the letter "c", the burets will not be emptying and refilling.

But if there is water in the burets, the concentration of the solutions will be changed, it would be more diluted, so it'll be necessary to empty and refill the burets.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
