How to Find the Concentration When You're Given the pH - Sciencing

The **pH** of a solution is equal to the base 10 logarithm of the H+ **concentration**, multiplied by -1. If you know the **pH** of a water solution, you can use this formula in reverse **tofindthe** antilogarithm and calculate the H+ **concentration** in that solution. Scientists use **pH** to measure **how** acidic or basic.

How do you calculate the pH of a solution when given the... - Socratic

The two expressions are opposites expressions. As the **pH** increases the pOH decreases and vice versa. Both values equal 14. To convert a **concentration** of into **pH** or pOH take the -log of molar **concentration** of the hydrogen ions or the molar **concentration** of the hydroxide ion **concentration**.

How Do I find the Concentration of H+ when I'm given pH?**How** can I do this without a calculator? I **found** some problems online, but have trouble understanding. If a soil has a **pH** of 4.7, what is the H+ **concentration** of the soil solution? **pH** = -log [H+] 4.7 = -log [H+] 4.7 = -(- 5) - 0.3; 100.3=2.0 (the -5 tells you the number of positions to move the decimal point to.
