The h30+ concentration of a solution is equal to 0.8 m. what is the ph of the solution?

a.) ph = 0.1
b.) ph = 1.1
c.) ph = 2.1
d.) ph = 10.1

option A= pH = 0.1

Explanation:

Given data:

Concentration of H₃O⁺ = 0.8 M

pH = ?

Solution:

pH = -log [H₃O⁺]         H₃O⁺ = H⁺

pH = -log [0.8]

pH = - (-0.097)

pH = + 0.1

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
