Answer:
The correct answer is option d.
Explanation:
..[1]
..[2]
moles of sodium thiosulfate solution = n
Molarity of the sodium thiosulfate solution = 0.150 M
Volume of sodium thiosulfate solution used = 0.890 mL = 0.00089 L
According to reaction [2], 2 moles of sodium thiosulfate reacts with 1 mol .
Then , 0.0001335 mol of sodium thiosulfate will reacts with:
of
Moles of = 0.00006675 mol
According to reaction [1], 1 mol of is obatnied from 1 mol of NaClO.
Then 0.00006675 mol of will be obtained from:
Mass of 0.00006675 mol of NaClO=
0.00006675 mol × 74.44 g/mol = 0.00496887 g
Mass of sample = 0.0854 g
Percentage of NaClO in sample:
x = 0.83 L
