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
The 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.

What happens when sodium formate reacts with soda lime?
When sodium formate reacts with soda lime, it forms sodium hydroxide and calcium carbonate. Sodium hydroxide is a strong base, while calcium carbonate is a weak base that can act as a buffer.
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.
What is the name of this compound---HCOOCH3----and the functional group present in it this compound reacts only with Na and not with any other forms of sodium compounds?
The compound is called methyl formate. The functional group present in it is the ester group (-COO-). Methyl formate reacts specifically with elemental sodium (Na) to form sodium formate and hydrogen gas.
Sodium formate is heated with conc sulphuric acid?
When sodium formate is heated with concentrated sulfuric acid, it undergoes dehydration to form sodium oxalate and water. This reaction typically occurs at elevated temperatures and can be used as a method for preparing sodium oxalate.
What is the pH of sodium of yougurt?
Sodium in yogurt hasn't a pH !
What happens to formic acid when sodium hydroxide is added?
When sodium hydroxide is added to formic acid, a neutralization reaction occurs. Formic acid (HCOOH) reacts with sodium hydroxide (NaOH) to form sodium formate (HCOONa) and water (H2O). This reaction increases the pH of the solution.
What is the pH of sodium sulphate?
The pH of a sodium sulfate solution is typically neutral, around 7, since sodium salts are made up of ions that do not affect the pH significantly.
Does sodium hydroxide have pH 7?
No, sodium hydroxide (NaOH) does not have a pH of 7. Sodium hydroxide is a strong base and has a pH greater than 7. The pH of a solution of sodium hydroxide depends on its concentration. A 0.1 M solution of NaOH has a pH of 13.
