Preparation |
: |
2.784 g in 1000 mL Dissolve 2.784 g of potassium bromate in water to make 1000 mL |

|
Standardization |
: |
Transfer
an accurately measured volume of about 40 mL of the solution to a
glass-stoppered flask, add 3 g of potassium iodide, and follow with 3 mL of
hydrochloric acid. Allow to stand for 5
minutes, then titrate
the liberated iodine
with 0.1 N sodium thiosulfate VS, adding 3 mL of starch TS as
the endpoint is approached. Correct for a blank run on the same quantities of
the same reagents, and calculate the normality. Preserve
in glass-stoppered bottles, protected from light |
