What is the pH of a solution if [H3O+] = 2.00x10-5 M? Include two digits past the decimal in your answer.
A solution has a pH value of 3.90. What is the pOH for the solution? Include one digit past the decimal in your answer.

1) pH = 5.20

2) pH = 4.70

3) pOH = 10.1

Explanation:

What is the pH of a solution with [OH- ] = 1.60x10-9 M?

Step 1: Data given

[OH-] = 1.60 * 10^-9 M

Step 2: Calculate pOH

pOH = -log[OH-]

pOH = -log [1.60*10^-9]

pOH = 8.80

Step 3: Calculate pH

pH = 14 - pOH

pH = 14 - 8.8 = 5.20

What is the pH of a solution if [H3O+] = 2.00x10-5 M?

[H3O+] = [H+] = 2.00 * 10^-5 M

pH = -log[H+]

pH = -log[2.00*10^-5]

pH = 4.70

A solution has a pH value of 3.90. What is the pOH for the solution?

pOH = 14 - pH

pOH = 14 -3.90 = 10.1

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
