What is the pH of 3.33 x 10^-3?
Write your answer to the nearest hundredth.

The answer to your question is below

Explanation:

1)

Data

pH = ?

[H⁺] = 7.9 x 10⁻¹² M

Process

1.- Write the formula of pH

pH = -log[H⁺]

2.- Substitution

pH = -log[7-9 x 10⁻¹²]

3.- Result

pH = 11.10

2)

Data

pH = ?

[H⁺] = 3.33 x 10⁻³ M

Process

1.- Write the formula of pH

pH = -log[H⁺]

2.- Substitution

pH = -log[3.33 x 10⁻³]

3.- Result

pH = 2.48

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
