Does the pH of phosphate buffer change on addition of sodium chloride?
It changed pH. I have to adjust back with NaOH
What happens to pH when NaOH is added to buffer?
Quantity matters. If there is a lot of buffer (in terms of moles) and relatively little NaOH then the buffer will prevent any change in pH. If there is relatively more NaOH than buffer, then of course the pH will rise.
How will you prepare propane from sodium salt of fatty acids?
by heating sodium butanoate with quick lime i.e dry mixture of NaoH and Cao
How do you prepare a 50 percent of NaOH solution?
Dissolve slowly 50 g NaOH in 100 mL water; advertisement: sodium hydroxide solution is dangerous !
Is NaF and NaOH a buffer?
yes
How do you prepare 0.01M sodium borate buffer?
Weigh the correct mass of boric acid corresponding to 0.01M adjust the pH using NaOH
How do you prepare sodium succinate buffer?
Prepared 0.5M succinic acid and 0.5 NaOH and adjusted pH to desired value
How you prepare sodium chloride?
Sodium chloride is the result of this reaction: NaOH + HCl = NaCl + H2O
What is the dissolution of sodium hydrogen carbonate?
I guess it would be NaOH and CO2. This explains why it is an alkaline buffer
Does the pH of phosphate buffer change on addition of sodium chloride?
It changed pH. I have to adjust back with NaOH
How do prepare sodium chloride?
Reactions are: 2Na + Cl2 = 2NaCl NaOH + HCl = NaCl + H2O

What acids should be used to prepare sodium chloride?
The hydrochloric acid: HCl + NaOH = NaCl + H2O

Is NaF and NaOH a buffer?
yes
How do you prepare phosphate buffer pH 7.4 using potassium dihydrogen orthophosphate?
Add 250 ml of 0.2M KH2PO4 to 393.4 ml of 0.1M NaOH
