The total volume required to reach the endpoint of a titration required more than the 50 ml total volume of the buret. an initial volume of 49.13±0.06 ml was delivered, the buret was refilled, and an additional 1.99±0.06 ml was delivered before the endpoint was reached. the titration of a blank solution without the analyte required 0.35±0.04 ml . calculate the endpoint volume corrected for the blank and its absolute uncertainty.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
