Question

The pH of solution A is 2.4​, while the pH of solution B is 9.4.

Answer 1

Answer:

Given:

The pH of solution A = 2.4

The pH of solution B = 9.4.

Solution:

The hydrogen ion  concentration is the amount of hydrogen ions present in the given solution usually expressed in terms of moles pere litre .

(A) hydrogen-ion concentrations of the solution.

$H^+= 10^{-pH}$

Now,

The hydrogen ion concentration of the solution A

$H^+= 10^{-2.4}$

$H^+= 3.981\times 10^{-3}$

Similarly

hydrogen ion concentration of the solution B

$H^+= 10^{-9.4}$

$H^+= 3.981\times 10^{-10}$

​(b) The hydrogen ion concentration of solution A $3.981\times 10^{-3}$ is and the solution B is $3.981\times 10^{-10}$

so we can conclude that the hydrogen ion concentration of solution A  is   $10^ 7$ times greater than solution B

(c) The solutions A and Solution B differ by 7 order of magnitude
