Question

What is the pH of a most acidic solution among the following?
(A) 1
(B) 6
(C) 9
(D)10
(E) 14

Answer 1

Hint: To solve this question we need to refer to the pH scale as it tells us about the acidity and the basicity of the elements, as in this question, we have been given the pH values of different solutions.

Complete answer:
We have been provided with the pH values of various solution: 1, 6, 9, 10 and 14,
We need to tell the most acidic solution out of these,
So, for that:
Firstly, we will talk about the pH scale,
So, pH scale is used to specify the acidity and basicity of a particular solution:
In a pH scale we know that acidic solutions have lower pH values which means lower the pH value of the solution more acidic it is,
Similar is for the basicity, basic solutions have higher pH values which means higher the pH values of the solution more basic it is,
So, as we need to tell the most acidic so, for that we just need to find the lowest pH values out of all,
So, the pH values we have are: 1, 6, 9, 10, 14
Out of these 5 as the first solution has the least pH value so, it is the most acidic out of all these.

So, from this we can conclude that the correct option is (A).

Note:
pH also plays an important role in our daily life, as in our digestive system: we know that the pH of our stomach is acidic which helps in the digestion of the food, but when the level of acid increases due to indigestion, pain and irritation can be caused in the stomach.
