### Why isn't an Acid-base titration curve linear? [duplicate]

Sorry if this is a stupid question, but why is a acid-base titration curve not linear? As you add more acid solution to a basic solution, shouldn't the pH of the basic solution slowly go up in ...

### Titration curve of strong acid with strong base [duplicate]

I have a question regarding the titration curve for $\ce{HCl}$ titrated with $\ce{NaOH}$. Why does it look like it does, with a steep slope near the equivalence point and a flat slope at the beginning ...

### How to determine the pH of a mixture of two weak acids?

We have two solutions: Solution 1 is $\ce{HCOOH}$, its concentration is $c_1 = \pu{10^-2 mol/l}$, its volume is $V_1 = \pu{50 ml}$, and its $\mathrm{pH}_1 = 2.9$. Solution 2 is $\ce{CH3COOH}$, its ...

### What is causing the buffer region in a weak acid - strong base titration?

For the buffer region in this, why does it stop the pH from increasing? At the start: $$\ce{CH3COOH + NaOH -> CH3COONa + H2O}$$ Which means there will be a high amount of salt in the solution, ...

### Inflection point, slope, and equivalence point in a titration

My textbook, Harris 7th Edition Quantitative Chemical Analysis, says: In titrations involving 1:1 stoichiometry of reactants, the equivalence point is the steepest point of the titration curve. ...

### Why is there an increase in the pH at the start of a titration between a weak acid and a strong base?

Why is there an increase in the pH at the start of a titration between a weak acid and a strong base even though there is acid already present to neutralize it? My intuition says that there should not ...

### Why is the vertical part of a titration curve longer for a strong acid by a strong base than for a weak?

As the title says, I would like to understand chemically why this occurs. My theory behind it is that in the former case both are completely dissociated, and so at the equivalence point (and ...

### pH Curves for Titrations

Why does the pH rapidly increase near the equivalence point during--why does the slope of the graph of a pH curve sharply increase around this area?

### pH Curves- Anomalies

In class, the other day, we were discussing pH curves. Assume that I have HCl and NaOH of concentration 1 mol/mL. Now, consider that I have 50mL of HCl, and begin adding small quantities of NaOH. I ...
