Problem NT-1: 2 pts Find the pH of a formic acid solution that was is prepared by adding 0.280 g of formic acid to a volumetric flask and bringing the final volume to 1.44 L by adding water.

Solution

Moles of formic acid = (0.280/46.03) = 0.0061

MOlarity = 0.0061 / 1.44 =0.0042 M

pH = - log [H+] = - log 0.0042

pH = 2.37
