Which one of the following solutions having same concentration will have lowest pH value?
(1) hydrochloric acid
(2) lemon juice
(3) water
(4) sodium hydroxide
Answers
Answer:
HCl
Explanation:
Hydrochloric acid being a strong acid will have the lowest pH value of 1 while NaOH will have a pH value of 14,being a strong base
Water will have its pH value as 7 while lemon juice will have its pH value around 4-5
Hydrochloric acid having same concentration will have lowest pH value.
Explanation:
The pH-scale ranges between 0 and 14. Acids have a pH less than 7 while bases have a pH greater than 7.
Hydrochloric acid is a solid acid so it will have the lowest pH compared with other choices.
Hydrochloric acid: Hydrochloric acid is a colorless, Chemical inorganic device. There is a heavy pungent smell of hydrochloric acid. It is known as highly acidic and can strike the skin over a broad range of composition, as the chloride of hydrogen dissociates entirely in aqueous solution.
Therefore the correct answer is Option (1) hydrochloric acid
