To calculate the pH of a weak acid, it is important to note that pH has no units, thus it is required to define it with H+ ion concentration.
The answer is C and since the acid is very dilute we have to consider the ionization of water, too. I don't get how you can calculate the pH considering that acid dissociation is NOT negligible, can someone please explain what steps to take and how the answer is C? Thank you Logged...

By using the Henderson - Hasselbalch equation, the pH of the solution can be determined using pH=pKa+log([base][acid]) Answer and Explanation:1 Apply the Henderson - Hasselbalch equation to solve the problem. That is, pH=pKa+log(...
To solve the problem, we need to calculate the degree of dissociation (α) of the weak acid HA when HCl is added to the solution. Here’s a step-by-step solution:Step 1: Determine the initial concentrations Given: - Number of m
Experts are tested by Chegg as specialists in their subject area. NO2 dissolves very well in water react with water to give nitrous acid and nitric acid. It is used to destroy the potentially explosive sodium azide. Just because a teacher is good at chemistry, this is no indication of thei...
To calculate the pH of a salt solution formed from a weak acid and a weak base, we can use the following formula:

(Table1). To calculate the effect of DIC increase on bottom water pH decrease, we have modified the popularly used CO2SYS program to include H2S–HS−and NH3–NH4+species in the acid–base equilibrium calculations as the bottom water in August contains these reduced chemical species (Methods...
In general, charge density cannot be estimated from pH alone in the presence of other ion species. For simplicity, we considered the case that molecules could be ionized to monovalent ions in the absence of buffer electrolytes composed of weak acid and/or weak base. We also did not consider...
