For any acid pH always <7 !!
Without an 'acid Ka value('s)'-table figures of this diprotic weak, but relatively strong acid one can only guess for a good estimate:
- If it were strong: 0.7
- If it were as weak as acetic acid: 3.9
- In reality it is between 1 and 2 so pH about 2.0 - 2.5 ?? seems the best guess
- If it were as weak as acetic acid: 3.9

Why 2N sulphuric acid is used in oxalic acid estimation?
This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
What is pH 7.0 an acid base or neutral solution?
Anything with a pH of 7 is neutral
What happens to the buffer solution pH 7 when acid is added?
When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
Does a weak acid resist a change in the pH?
It's easier to change the pH of a weak acid than a strong acid.
Describe a solution that contains a buffer?
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
How many milliliters of a 0.270 M solution are needed to react completely with 3.245 g of oxalic acid?
The answer depends on which compound is in the 0.270M solution to react with oxalic acid, and sometimes also at what temperature and pH value this reaction is taking place.

Will H2C2O4 increase decrease or no change in the pH when added to water?
the pH will decrease slightly as oxalic acid is a weak acid.
Why would you add sulfuric acid to a mixture of oxalic acid and sodium oxalate?
This is an example of a buffer solution. if the sulfuric acid were added to a plain glass of water, it would have a massive change in pH. However, the buffer action of the oxalate-oxalic acid solution will decrease this change to something very minor (demonstrably to only hundredths or thousands, if the solution is made well, of the change it would have on pure water).
How does the presence of an acid in a water solution affect of the pH of the solution?
The presence of an acid lowers the pH of the solution in water.
How does presence of an acid in a water solution affect the pH of the solution?
The presence of an acid reduces the pH.
How does the presence of an acid in a water solution affects the pH of the solution?
The presence of an acid reduces the pH.
How does the presence of an acid in a water solution affect the pH of solution?
The presence of an acid reduces the pH.
How does a the presence of an acid in a water solution affect the pH of the solution?
The presence of an acid reduces the pH.
How does the presence of an acid in water solution affect the pH of solution?
The presence of an acid reduces the pH.
How does the presence of an acid in water solution affect the pH of a solution?
The presence of an acid reduces the pH.
How does the presence of an acid in a water solution affect of pH of the solution?
The presence of an acid reduces the pH.
