If this dissociation is limited (relative to strong acid), then the compound is known as a weak acid. The acid dissociation is then represented as an equilibrium of the weak acid, conjugate weak base and hydronium ion. The constant for this equilibrium is "Ka". A s...
What is (H3O+) in a solution of 0.075 M HNO2 and 0.030 M NaNO2?Nitrous acid, HNO2, has a Ka of 7.1 x 10^-4. What is the H3O+ in a 0.60 M solution of HNO2?Which of the acids below will have the lowest pH in a 0.10 M solution of...
How can you estimate the pH range of an indicator's color change? A certain indicator, HA, has a Ka value of 0.000025. The protonated form of the indicator is red and the ionized form is yellow. a. What is the pKa of the indicator? b. ...
