A student performs a redox titration to determine the percent by mass of chlorate in an allergy tablet. The chlorate is titrated with iodide ions until the end point. The student reported that 29.50 mL of 0.100 M KI solution was required to reach the end point of a titration when 10 allergy tablets containing chlorate as the main active ingredient are dissolved in 25.00 mL of distilled water. What mass in grams of chlorate is present in the 10 allergy tablets? Use the Balanced chemical equation to answer the question.
6, 1, 6, 3, 1, 3

Hint: this is a net ionic equation, so spectator ions have been removed!

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

the correct answer is:

a. formation of precipitation
