## What is the pH range of phosphate buffer?

5.8 to 8.0
Phosphate Buffer (pH Range = 5.8 to 8.0) You can then adjust the final pH using a sensitive pH meter.

How will you prepare 0.05 M sodium phosphate buffer pH 7?

Dissolve 2.322 g of dipotassium hydrogen phosphate in water and dilute to 200.0 ml with the same solvent. Mix 188.8 ml of solution I and 11.2 ml of solution II. If necessary, adjust to pH 5.6 using solution I or solution II. To adjust pH you can simply add 1 M NaOH drop wise, not in excess.

How do you make sodium phosphate buffer?

METHOD

1. Dissolve 35.61 g of Na2HPO4•2H2O and 27.6 g of NaH2PO4•H2O separately in H2O.
2. Adjust the volume of each solution to 1000 mL. Store the stock solutions for up to 6 mo at 4°C.
3. To prepare the buffer, mix the stock solutions as follows: i.
4. Check the pH of the solution at room temperature.
