Q. The pH of a buffer solution is 4.745. When 0.044 mole of is added to I lit. of the buffer, the pH changes to 4.756. Then what is the buffer capacity?
for Ba(oh)2 means 0.44*2=0.088 because there are 2{oh}-
buffer capacity=no.of moles of solute / change in ph
change in ph =4.756-4.745=0.011
buffer capacity=0.088/0.011=8
buffer capacity=no.of moles of solute / change in ph
change in ph =4.756-4.745=0.011
buffer capacity=0.088/0.011=8
