Question

An unknown solution has an H+ concentration of 10-12 moles per liter. Which of the following statements correctly describes this solution? The solution is basic in nature./ The solution is acidic in nature. /The solution is neutral in nature.

Answer 1

The pH of the solution 12 which means that solution is basic in nature.

Step-by-step explanation:

The pH of the solution is defined as negative logarithm of hydrogen ions concentration in a solution. Mathematically written as:

`pH=-\log[H^+]`

Given concentration of hydrogen ions=
`[H^+]=10^(-12) M`

`pH=-log[10^(-12)]=12`

• Solution with pH less than 7 are considered as acidic as solutions.
• Solution with pH more than 7 are considered as basic as solutions.

The pH of the solution 12 which means that solution is basic in nature.

Answer 2

Given the concentration of H+, we can calculate the pH through the formula pH= -log(H+). In this problem, the pH is 12. Hence the solution is basic in nature.
