What scale measures the concentration of hydrogen ions?
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
What two factors are involved in determining the exact pH of a buffer?
The molarity of the buffer and the hydrogen concentration of the buffer.
Why does the pH drop so fast during titration at a certain point?
When there is a buffer present, the buffer makes it difficult to change the pH of a solution. Say for instance a buffer keeps the pH around 6.5 +/- 0.2 . The buffer only works when the pH is in this range. If too much acid or too much base is added, taking the pH out of this range the pH will change quickly, even if only a little extra base or acid is added to the solution.
What is the relationship between concentration of ions and the pH scale?
pH = -log10([H3O+]).
A scale indicates the relative concentration of hydrogen ions in a solution?
pH scale

What is the PH when buffer is added to water?
Since we do not know the buffer or its concentration, we cannot provide an answer.
Effect of Diluting a buffer?
The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
What is acid measured on the pH scale?
An acid would be on the left side of a pH scale
Why was your measured pH level of the buffer solutions different from the calculated values?
A

How does the concentration of H affect the number on the pH scale?
The meaning of a higher H+ concentration is a low pH.
What scale is pH?
PH scale is a scale that shows the substance is PH ....... Example: The substance is PH 7, so it is neutral The substance is PH 3, so it is acid The substance is PH 10, so it is alkali
If you have a lower pH will you have higher proton concentration?
Yes. The pH scale is an inverse log scale of the [H].
If 1.0L of this buffer contains an acid concentration of 0.50M and a conjugate base concentration of 0.50M what is the buffer pH?
When the concentration of the weak acid is the same as the concentration of the conjugate base, the pH will be equal to the pKa of the weak acid. This is because from the Henderson Hasselbalch eq:pH = pKa + log [acid]/[conj.base] and when [acid] = [conj.base], the log of 1 = 0 and pH = pKa.
How do you prepare pH buffer soultion?
Decide on the concentration of the buffer, use 1L to be simple PH for your buffer should be within one pH unit from the pKa of the acid/conjugate base use Henderson Hasselbalch Equation pH = pKa + log ([Base]/[Acid]) For a 1 M buffer [Acid] + [Base] = 1
