Question

Type the correct answer in the box. Round your answer to the nearest hundredth.

A solution has a hydronium concentration of 4.7 × 10-11. What is the pH of the solution?
The pH of the solution is ________ .

(FREEBEE: The awnser is 10.33)

Answer 1

this is formula to find pH. -log[H^+]
now press calculator -log[4.7×10^11] and you will get 10.33

Answer 2

10.33

Step-by-step explanation:

pH is negative logarithm of the hydrogen ion concentration.

Given, hydronium ion concentration = 4.7 x 10⁻11

pH = - log[H₃O⁺] = - log(4.7 x 10⁻11) = 10.33

A pH below 7.0 means the solution is acidic. Neutral pH is at 7.0. For pH above 7.0 the solution is basic
