What is the pH of a solution has a hydrogen ion concentration of 6.3 x 10–10 M? Show work
NISA [10]

Answer:

pOH = 4.8

pH = 9.2

Explanation:

Given data:

Hydrogen ion concentration = 6.3×10⁻¹⁰M

pH of solution = ?

pOH of solution = ?

Solution:

Formula:

pH = -log [H⁺]

[H⁺] = Hydrogen ion concentration

We will put the values in formula to calculate the pH.

pH = -log [6.3×10⁻¹⁰]

pH = 9.2

To calculate the pOH:

pH + pOH = 14

We will rearrange this equation.

pOH = 14 - pH

now we will put the values of pH.

pOH = 14 - 9.2

pOH = 4.8

How do you Convert 19mL to pL?
s2008m [1.1K]

Picoliter is a unit of measurement for liquids.

One picoliter = 1×10⁻⁹ mililiters

So:

19 mL ---- x pL

1×10⁻⁹ mL ---- 1 pL

1×10⁻⁹x = 19

x = 1,9 × 10¹⁰ pL

or 19,000,000,000 pL

Answer: 1.9 × 10¹⁰ pL
