Dissolve 25g of Ammonium acetate in 25ml of water and add 38ml of 7M hydrochloric acid. Adjust the pH of the solution to 3.5 with either 2M hydrochloric acid or 6M ammonia and dilute with water to 100ml
can I make sodium acetate buffer 0.2M Ph=5 whit sodium acetate buffer 3m Ph=5 solution?
The pH of water is approximatly 7 (a neutral pH), and the acetate buffer has an acidic pH (less than 7) so when you add distilled water to the buffer the pH will increase.
To prepare the buffer using solid form reagents, prepare a 0.1 M ammonium acetate solution by dissolving 7.7 g ammonium acetate in a 1000 ml water. Adjust 1 L of this solution to pH 4.5 by adding acetic acid (about 8 ml) and 5 ml of 1 M p-TSA (equivalent to 5 mM p-TSA).
the pH of ammonium acetate buffer can be adjusted with glacial acetic acid (concentrate or diluted )
pH of sodium acetate buffer is 4.6 and most of the proteins have 4.8 isoelectric pH (pI), so buffer maintains the pI of casein in the casein estimation from milk

Not exactly sure what the question is asking, but sodium acetate will not buffer at pH 8. It is an ok buffer in the pH range of maybe 3-5 or so. Acetic acid is the weak acid of this buffer with a pKa near 10^-5. To make a decent buffer at pH 8, one needs a weak base, or a weak acid with a pKa closer to 8.
The following table is extracted from the Internet:* For pH=3: mix 982,3 mL 0,1 M acetic acid with 17,7 mL 0,1 M sodium acetate* For pH=4: mix 847,0 mL 0,1 M acetic acid with 153 mL 0,1 M sodium acetate* For pH=5: mix 357 mL 0,1 M acetic acid with 643 mL 0,1 M sodium acetate* For pH=3: mix 52,2 mL 0,1 M acetic acid with 947,8 mL 0,1 M sodium acetate
