The pH of a solution containing 0.1 mM H+ is _______ ( 1mM = 10-3M)

Taya2010 [7]

Answer:

The pH of a solution containing 0.1 mM H+ is 4

Explanation:

The pH of any solution is given by the following mathematical equation -

$pH = -log[H_{+}]\\$ ----------- Equation (A)

Where,

$H_{+}$ = the concentration of hydrogen ion in the solution.

Given

$H_{+}$

= $0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\$

Substituting the given value in equation (A) , we get -

$pH = -log[10^{-4}]$

$= -(-4)\\= 4$

Hence, The pH of a solution containing 0.1 mM H+ is 4

If a red-flowering plant was crossed with a white-flowering plant what would the phenotypes of the offspring be?
