Acid Base Reactions

Step 1: Use the formula for dissociation.
The dissociation of a weak acid is governed by the equation: Where is the dissociation constant, is the concentration of the acid, and is the degree of dissociation. Step 2: Given information.
The acid is 10\% dissociated at 0.05 M, so we can use this to calculate . Now we can substitute into the dissociation equation to find the value of . Once is calculated, use it to determine the dissociation at 0.15 M by substituting into the dissociation equation again.
