What does a large Ka value indicate about an acid?
Remember, strong acids have high dissociation constants.
Write the formula for how Kw relates to Ka and Kb.
It's a product of the two constants.
What does Ka measure?
Remember, it’s about how well the acid can release protons.
True or False: A weak acid has a large value for Ka.
Think about what categorical strength means.
A 0.1 M acetic acid solution is titrated with NaOH. Calculate the pH at the equivalence point.
Remember that pH will be affected by the weak base generated from the weak acid.
Given the Ka of an unknown acid is 4.0 × 10⁻⁷, determine if its conjugate base is strong or weak.
Remember, a high Ka will indicate a low Kb.
