17.4: Titrations and pH Curves - Chemistry LibreTexts

The pKb of ammonia is 4.75 at 25°C. Answer. As shown in part (b) in Figure 17.4.3, the titration curve for NH3, a weak base, is the reverse of the titration curve for acetic acid. In particular, the pH at the equivalence point in the titration of a weak base is less than 7.00 because the titration produces an acid.

Neutralization reaction between ammonia and nitric acid

Your answer is very close to the answer given, except for the following two tidbits (the first being more significant). An acid-base reaction is not the exchange of a hydrogen atom $ce{H}$.It is the exchange of a hydrogen ion (or proton) $ce{H+}$.Thus your answer should be: $$ce{NH3(aq) +HNO3(aq) -> NH4+(aq) + NO3-(aq)}$$ The given answer combines the two ions produced into a single compound.

ChemTeam: Molarity Problems #11 - 25

Problem #25: A solution of calcium bromide contains 20.0 g dm-3. What is the molarity of the solution with respect to calcium bromide and bromine ions. Solution: MV = mass / molar mass (x) (1.00 L) = 20.0 g / 199.886 g/mol x = 0.100 M When CaBr 2 ionizes, two bromide ions are released for every one CaBr2 that dissolves. That leads to this:
