Why you use pH 10 buffer in EDTA titrtion?
because EBT work best in that pH
What is the need for an ammonical buffer solution in the determination of hardness of water by edta titration?
during the complexometric titration using edta it is very necessary to maintain the ph of the solution near about 10 so we use ammonium chloride buffer if we will not use this buffer dring the titration ph of sol. will ho lower side
Is it possible to make a buffer of boric acid and borax?
Yes, this buffer works in the range 8-10 pH.
Why is water a good pH buffer?
Water is not a good pH buffer.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
Over what pH range would Glycine be a useful buffer?
Glycine is a useful buffer anywhere from 8.6 to 10.6 range. By utilizing Glycine stock agents in the buffer, it's entirely possible to create 21 different PH levels.

What is the pH of glycine?
Neutral
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
What is the use of buffer?
To maintain constant the pH of a solution.

Is the buffer supposed to keep the pH of a solution at 7?
Some buffer solutions maintain pH at 7, but others have different pH values. It is common to have buffers with pH values of 4, 7, and 10 for calibrating pH meters, for example.
Is it possible to make a buffer of boric acid and borax?
Yes, this buffer works in the range 8-10 pH.
Why is water a good pH buffer?
Water is not a good pH buffer.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
Is HCl a pH buffer?
No, it is not a buffer.
What is the difference between NIST buffer solution and USA buffer solutions?
When setting up your pH meter you need to specify that the standard solutions are NIST, USA, China or Custom standards. Typically pH meters will automatically identify the pH 7 buffer standard as 6.86 for the NIST selection and 7.00 for the USA selection. The pH 4 buffer standard value will be identified as 4.01 for the NIST selection and 4.00 for the USA selection. The pH 10 buffer standard value will be identified as 9.18 for the NIST selection and 10.00 for the USA selection. A "Custom" selection on your pH meter will allow you to make your special selection of the standards you want to use. Read the calibration meter set up section of your pH meter manual and check your pH buffer standard labels to ensure you match your pH meter set up to the standards you intend to use.
