For pH = 7,0: 756 mL disodium hydrogen phosphate (Na2HPO4) solution 0,1 M (14,2 g/L) + 244 mL hydrochloric acid (HCl) solution 0,1 M
dude i cant tell you way to private you better know this all ready use your bean ok it helps you to learn
Sodium phosphate.
Without phosphate you can't.
Cfjn
Did you mean Na2HPO4 ?(I cannot find a reference to a compound Na4HPO4 )Na2HPO4 is usually called disodium phosphate.Other names are sodium hydrogen phosphate. Phosphates are notorious for haveng multiple names.It is a salt containing the HPO42- ion. There is a "picture odf the structure in wikipedia see disodium phosphate.
you can prepare 20nM sodium phosphate buffer pH7.0. calculate mass of enzyme and dilute in volume buffer to reach concentration you want. good luck
can I make sodium acetate buffer 0.2M Ph=5 whit sodium acetate buffer 3m Ph=5 solution?
dissolve the 12 g of crystals of sodium phosphate in water to make 1oo ml
For the preparation of a solution with the pH=7,00:Add 29,1 mL sodium hydroxide solution 0,1 M to 50 mL potassium dihydrogen phosphate solution 0,1 M.
I don't know how to make the solution below. Low salt buffer: 10 mM phosphate buffer, 10 mM NaCl, pH 7.4. Could you tell me the method in detail?
1 M Sodium Phosphate Buffer Stock Solution (1 liter) Protocol # Solution A: Dissolve 138.0 g NaH2PO4?H2O in 1 liter dH2O (pH 7.0). # Solution B: Dissolve 142.0 g Na2HPO4 in 1 liter dH2O (pH 7.0). # Mix 423 ml Solution A with 577 ml Solution B. # Autoclave and store at room temperature.
10ml of 0.4M Citric acis solution 90 ml of 0.4M sodium phsophate dibasic solution 12.22g NaCl (tomake 150mM ionic solution) or 6.38g to make 100mM ionic strength. make up volume upto 2000ml with water. You should not need to pH this buffer . :)

Dissolve 3,2788 g Na3PO4 in 1000 mL of this water solution.
Sodium phosphate.
Without phosphate you can't.
Aqueous sodium phosphate and aqueous iron nitrate react to produce aqueous sodium nitrate and solid iron phosphate.
