The concentration of H3O+ in the buffer prepared in the previous question is 1.80×10−5 . What is the pH of the solution?

pH = 4.7

Explanation:

Given data:

Concentration of H₃O⁺ = 1.80×10⁻⁵ M

pH of solution = ?

Solution:

Formula:

pH = -log[H₃O⁺]

pH = -log[1.80×10⁻⁵]

pH = 4.7

pH of solution is 4.7.

there is none because earth is stationary and flat.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
