Ph Calculator

Our pH Calculator makes finding the pH of any acid or base solution super easy. This free tool helps you solve chemistry problems quickly and accurately. pH stands for “potential of Hydrogen” or “power of Hydrogen.” It tells us how acidic or basic a solution is.

How Ph Calculator Works

Our calculator uses the formula: pH = -log[H⁺]

Don’t worry about memorizing this! Just understand:

• We measure the concentration of hydrogen ions
• Use math (logarithm) to convert to pH scale
• Our calculator does all the math for you

Using the Calculator: Step-by-Step Guide

Follow the given steps to use PH Calculator:

Step 1: Choose What to Calculate

Your calculator has a dropdown menu. Select “pH” to find the pH value.

Step 2: Enter Your Concentration

Type the concentration of your solution in the number box.

Units Available:

• M (Molar): Most common in chemistry class
• mM (Millimolar): 1/1000 of a molar
• μM (Micromolar): 1/1,000,000 of a molar
• nM (Nanomolar): Very small concentrations

Step 3: Enter Chemical Name or Formula

Type your chemical in the text box. Examples:

• “HCl” (hydrochloric acid)
• “NaOH” (sodium hydroxide)
• “Hydrochloric acid”
• “Sodium hydroxide”

Step 4: Click Calculate

Hit the “Calculate” button and get your answer instantly!

Real Example: Finding pH of HCl

Let’s calculate the pH of a 0.01 M hydrochloric acid solution:

Given Information:

• Chemical: HCl (hydrochloric acid)
• Concentration: 0.01 M
• HCl is a strong acid

Using Our Calculator:

1. To Calculate: Select “pH”
2. Enter Concentration: 0.01
3. Select Units: M
4. Enter Chemical: HCl
5. Click Calculate

Result: pH = 2 (acidic, as expected!)

Common PH Values

Everyday Items:

• Lemon juice: pH 2
