Sodium Formate is the salt of strong base and weak acid. It can formed by reaction with strong base sodium and weak acid Formic acid.
The PH will be =1/2Pkw+1/2Pka+1/2logC
kw is the dissociation constant of water.
ka is the dissociation constant of acid.
C stands for concentration of the salt in aqueous media.
P is denoted for antilog of the constants.
So, for this case,
PH=1/2*14+1/2*3.75+1/2*0.2=8.97

BeauThe pH of a 0.2 M solution of sodium formate would be around 8.4. Sodium formate is the sodium salt of formic acid, which is a weak acid. When dissolved in water, it will partially dissociate to release formate ions, which will react with water to produce hydroxide ions, increasing the pH.

Chemical formula of sodium formate?
The chemical formula of Sodium Formate is HCOONa
What is the pH of ammonium formate?
The pH of a 0.1 M solution of ammonium formate is approximately 6.0. This is because when ammonium formate dissolves in water, it undergoes hydrolysis to form ammonium ions and formate ions. The presence of these ions affects the pH of the solution.
What happens when sodium formate and soda lime are heated?
When sodium formate and soda lime are heated together, sodium formate decomposes into sodium carbonate and formic acid. The formic acid then reacts with the soda lime (a mixture of calcium oxide and sodium hydroxide) to form sodium formate again, releasing water and carbon dioxide as byproducts.
How do you test sodium formate in the laboratory?
One common test for sodium formate in the laboratory is the flame test. When sodium formate is heated in a flame, it will produce a yellow flame characteristic of sodium ions. Another method is using analytical techniques such as ion chromatography or titration to quantify the amount of sodium formate in a sample.
What is the pH of HCOOK?
The pH of a salt such as HCOOK (potassium formate) depends on its concentration in water. Generally, the solution will be slightly acidic due to the presence of the weak acid formate ions. The pH can be calculated using the dissociation constant of formic acid and the concentration of HCOOK.
