Correct question: A tool used for vegetable strainer,it is essential for various tasks from cleaning vegetables to straining pasta or tin contents.
Answer: The tool is called COLANDER.
Explanation:
In the kitchen, there are different types of equipments and utensils which makes work easier and faster. Examples of such equipment/ utensils includes:
--> graters,
--> cutleries ( spoon, fork, knife)
--> colanders
--> Pots
--> Blenders
These utensils are made up of rubber, plastics, wood, ceramics and stainless steel.
A Colander is an important kitchen utensil, a type of strainer with perforated holes. The holes allows fluid to drain leaving behind the solid part. It is usually bowl - shaped. It helps in performing the following roles in the kitchen:

--> straining of pasta
--> straining of tin contents
Colanders are usually made of stainless steel, plastics and ceramics.

Answer:
![[H_{3}O^{+} ] = 10^{-2}](https://tex.z-dn.net/?f=%5BH_%7B3%7DO%5E%7B%2B%7D%20%5D%20%3D%2010%5E%7B-2%7D)
mol/ L
Explanation:
Measure of [H₃O⁺] , i.e hydrogen ion concentration, indicates the acidity of the solution. The greater the concentration, the greater is the acidity. [H₃O⁺], this quantity can range from 10⁻¹ to 10⁻¹⁴ at ambient temperature(298K). This range is always temperature dependent.
Measure of acidity of a solution is expressed more conveniently using the notation of pH.
![pH = - log_{10}[H_{3}O^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log_%7B10%7D%5BH_%7B3%7DO%5E%7B%2B%7D%20%5D)
Using the above formula
![[H_{3}O^{+} ] = 10^{-(pH)}](https://tex.z-dn.net/?f=%5BH_%7B3%7DO%5E%7B%2B%7D%20%5D%20%3D%2010%5E%7B-%28pH%29%7D)
