Answer:
The hydronium ion concentration of the substance is 0,01 M.
Step-by-step explanation:
The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as
pH = -log (H 30+), and in this case we solve to calculate (H30 +):
(H30 +) = antilog -pH= antilog -2
(H30+)=0,01 M
