Ba(OH)2 is a strong electrolyte. Determine the concentration of each of the individual ions in a 0.300 M Ba(OH)2 solution.?

= 0.3 M

= 0.6 M

Explanation:

We can start wit the ioniation reaction:

We have the ions and . Now, we can calculate the concentration of each ion:

Concentration of

In balanced reaction we have 1 mol of and 1 mol of , so, we have a 1:1 mol ratio, with this in mind:

Concentration of

In balanced reaction we have 1 mol of and 2 mol of , so, we have a 1:2 mol ratio, with this in mind:

I hope it helps!

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
