The expression for dissociation or solubility of c d, carmina box, late c d, 2, positive plus c, o 3 to negative and k value is equal to 2.510 raised to power negative 16 point. We substitute the concentration into k, s p formula and calculated as so concentration h, 3 o positive equals k a h, 4, a c divided by negative substituting the .375 now moving towards k. A of h, 2 c 3 gives h 3, o positive and co 3 negative divides by h, 2 c 3. H, 3, o positive substituting the values 3.5810 raised to power negative 4 pint from k, a and c o 3 to negative concentration. We can determine the value of k. A so ka will be equal to concentration for c o 3 to negative, divided by 3.5810, raise to the power negative 4 rearranging the equation: cero 3 to negative terms to be 3.5810 or negative 4 divided. By turns out to be 2.0910 raised to the power negative 9, the concentration for cadmium can be calculated using as formula so c. D 2 positive will be equal to 2.09 multiply 10 raised to 1 negative 9 and camumbine concentration terms out to be.
