Suppose in an experiment to determine the amount of sodium hypochlorite in bleach, 0.0000524 mol K I O 3 were titrated with an u
11111nata11111 [884]

<u>Answer:</u> The amount of sodium thiosulfate required is 2.62\times 10^{-5} moles

<u>Explanation:</u>

Moles of KIO_3 solution given = 0.0000524 moles

The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:

2KIO_3+Na_2S_2O_3\rightarrow K_2S_2O_3+2NaIO_3

By Stoichiometry of the reaction:

2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate

So, 0.0000524 moles of potassium iodate will react with = \frac{1}{2}\times 0.0000524=0.0000262mol of sodium thiosulfate

Hence, the amount of sodium thiosulfate required is 2.62\times 10^{-5} moles

You need to use the formula--> P1V1= P2V2 (Boyles's law)

P1= 14 bar
V1= 312 mL
P2= ?
V2= 652 mL

now we plug the values into the formula.

(14 x 312) = (P2x 652)

P2= (14 x 312)/ 652= <span>6.70 bar</span>
