WebMental calculations can result in an exact answer or an estimated answer. For example, just below is a pH of 5.75. This is very close to a pH of 6 which would give [H 3 O +] equal to 1 x 10¯ 6 M. Since our pH is a bit less than 6, the [H 3 O +] will be a bit more than 1 x 10¯ 6 M. WebDetermine the [H3O+] and pH after adding 10.00 mL of titrant: You are going to titrate 20.00 mL of 0.150 M nitric acid, HNO 3 , with 0.100 M sodium hydroxide, NaOH. What volume of the 0.100 M NaOH solution will be required to reach the equivalence point of the titration?
