Question 14 (2 points)
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

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
