Explanation:
1.)Sodium acetate is a salt of weak acid (acetic acid) and strong base (NaOH).
It undergoes hydrolysis in aqueous solution.
CH
3
COONa+H
2
O→CH
3
COOH+Na
+
+OH

Acetic acid is weak acid and is partially dissociated whereas NaOH is strong base and completely dissociated.
Thus, the solution contains more number of hydroxide ions and less number of hydrogen ions. This makes solution alkaline.
Hence, the pH of an aqueous solution of sodium acetate is more than 7.
2.)citric acid
The acids in lemons are citric acid, which makes lemons tart, and ascorbic acid, which is vitamin C
3.)Formic acid, also known as formate or methanoic acid, belongs to the class of organic compounds known as carboxylic acids.
Dilute acids contain a large amount of water. A concentrated acid can be diluted with the addition of water. All acids may be organic or inorganic, releasing hydrogen ions (H+) in water.

Answer:
I am not a moderator or a star but still your answer is here⤵️:
i. It is sometimes produced in a laboratory experiment by the reaction of acetic acid, commonly in the 5–8% solution known as vinegar, with sodium carbonate ("washing soda"), sodium bicarbonate ("baking soda"), or sodium hydroxide ("lye", or "caustic soda"). Any of these reactions produce sodium acetate and water.
ii. citric acid:
A lemon is an acidic fruit with a pH ranging from 2 to 3. The acids in lemons are citric acid, which makes lemons tart, and ascorbic acid, which is vitamin C.
iii. Formic acid, also known as formate or methanoic acid, belongs to the class of organic compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Formic acid exists as a liquid, soluble (in water), and a weakly acidic compound (based on its pKa).
