What is the pH of a solution that has a hydroxide ion concentration of 1.0×10−9 M?

bogdanovich [222]

Answer:

$\boxed{\text{pH = 5.00}}$

Explanation:

Step 1. Calculate the pOH

pOH =-log[OH⁻]

pOH =-log(1.0 × 10⁻⁹)

pOH = 9.00

Step 2. Calculate the pH

pH + pOH = 14.00

pH + 9.00 = 14.00

$\boxed{\textbf{pH = 5.00}}$

A sample of gas has an initial volume of 22.6 L at a pressure of 1.67 atm. If the sample is compressed to a volume of 10.0 L : ,

Sphinxa [80]

Answer:

3.74 atmospheres

Explanation:

If the temperature is constant, then the formula is

V*P = V1 * P1

V = 22.6 L

P = 1.67 atm

V1 = 10.0 L

P1 = ??

=============

22.6 * 1.67 = 10 * P1

37.742 = 10 * P1

37.742/10 = P1

P1 = 3.742

Note there are 3 sig digs in each given, so the answer should be

P1 = 3.74 atmospheres
