Construct the expression for Ka for the weak acid, NH,. NH, (aq) + H,O(1)=H,0(aq) + NH,(aq) 1 Based on the definition of Ka, drag the tiles into the numerator or denominator to construct the expression for the given acid. Ko

In a 0.09 M solution of chlorous acid, what percentage of the acid is ionized to the chlorous anion, ClO2-? Ka = 1.1 x 10-2 include 3 significant figures in your answer

Aspirin (acetylsalicylic acid, C9H3O4) is a weak monoprotic acid. To determine its acid-dissociation constant, a student dissolved 2.00 g of aspirin in 0.600 L of water and measured the pH. What was the Ka value calculated by the student if the pH of the solution was 2.61? Express your answer numerically using two significant figures. • View Available Hint(s) ? Ka =
