a A 10L aqueous solution of 100M HCl b A 10L mixture of 100M

a) A 1.0L aqueous solution of 1.00M HCl

b) A 1.0L mixture of 1.00M H3PO4 and 1.00M HCl

c) A 1.0L mixture of 1.00M H3PO4 and .500M NaOH

d) A 1.0L mixture of 1.00M H2PO4- and 1.00M H3PO4

e) a 1.0L aqueous solution of .75M H2SO4

I\'ve looked everywhere, and I\'m still not sure how to calculate buffer capacities or determine what solution would have the highest. Please Help!

c) A 1.0L mixture of 1.00M H3PO4 and .500M NaOH
