▪ HNO3 → strong acid
▪ NaOH → strong base
▪ the reaction between a strong base and strong acid → no need to create an ICE chart
Balanced reaction: HNO3(aq) + NaOH(aq) → H2O(l) + NaNO3(aq)
Step 1: Calculate the initial amount (in moles) of the acid and base
moles HNO3 = 0.0112 mol
moles NaOH = 0.0100 mol
The amount of HNO3 is greater than NaOH, therefore there will be HNO3 left after the reaction
Step 2: Calculate the amount of HNO3 reacted
A 50.0-mL sample of 0.200 M sodium hydroxide is titrated with 0.200 M nitric acid. Calculate the pH of the solution, after you add a total of 55.6 mL 0.200 M HNO3.
