🤓 Based on our data, we think this question is relevant for Professor Cruz's class at LONESTAR.
What is the hydronium ion concentration of a 0.980 M acetic acid solution with Ka = 1.8 x 10-5? The equation for the dissociation of acetic acid is:
CH3CO2H (aq) + H2O (l) ⇌ H3O+ (aq) + CH3CO2- (aq).
a. 3.0 times 10-2 M
b. 4.2 times 10-2 M
c. 3.0 times 10-3 M
d. 42 times 10-3 M
e. There is not enough information to solve.
