A cylinder contains many pale blue balls and 3 purple balls. A box has a pale blue ball with the label H + and a purple ball with the label O H negative. Use the diagram of the solution and its key to answer the questions.

What type of solution is represented by the beaker?

Which would be a good estimate of the solution’s pH?

If you poured out half the solution in the beaker, the pH of the remaining solution would
.

what does the table look like

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 ratio of the conjugate base to the acid required to attain the desired ph.
