a few of the "newer" antacids contains sodium citrate Na3C6H5O7, as the effective, but more mild ingredient.
a) write a balanced equation representing the antacid effect of the citrate ion, C6H5O7^(3-)
b) will 500 mg of Na3C6H5O7 (258.1g/mol) or 500 mg of CaCO3 (100.1g/mol) neutralize more moles of hydronium ion? Assume that both the C6H5O7^(3-) and CO3^(2-) ions become fully protonated.
