0.472 M sulfuric acid was used to titrate a 0.388 M barium hydroxide solution. The initial volume reading on the acid buret was 34.42 mL and the final reading was 41.90 mL. If the initial reading on the base buret was 63.25 mL, what was the final volume reading on the base

The final volume reading on the base is 72.35 mL

Explanation:

To calculate the volume of base, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is

We are given:

Putting values in above equation, we get:

Final volume of barium hydroxide solution = Initial volume + Volume needed to neutralize = [63.25 + 9.10] = 72.35 mL

Hence, the final volume reading on the base is 72.35 mL

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
