The ion exchange capacity of a zeolite is determined experimentally as follows: 20.00 cm of 0.02030 M Ca?- solution is added to 0.1498 g of zeolite and the mixture is stirred for 20 min. The zeolite is removed from the solution by filtration and the filtrate is titrated to a hydroxynaphthol blue endpoint using 17.13 cm of 0.01955 M EDTA solution. Use the information above to calculate the ion exchange capacity i.e. moles of Ca2+ that can be absorbed by lg of the zeolite
