For h3po4 and h3bo3, does the subscript “3” of hydrogen in these two formulas seem to result in additional ions in solution as it did in group a? explain.

are weak electrolytes. They partially ionize in solutions as below,

The number of ions increase in solution apparently but this increase will be very less as these compounds are weak electrolytes, there will be a little increase in conductivity of these compounds in solutions. Unlike strong electrolytes these compounds show a very little increase in the concentration of ions although there is a subscript of 3 on hydrogen as these compounds partially ionize in solution.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
