## What is the relationship between pH pH and pOH pOH?

pH and pOH are related to one another; THEY ARE NOT INDEPENDENT OF EACH OTHER. As pH increases, pOH decreases. As pH decreases, pOH increases. By knowing what ion you are measuring on which scale, this will tell you whether or not the solution is acidic or basic.

**Is a high pOH acidic or basic?**

acidic

pH and pOH denote the negative log of the concentration of hydrogen or hydroxide ions. High pH means that a solution is basic while high pOH means that a solution is acidic. Neutral solutions have pH and pOH of 7.

### Is pOH 9 acidic or basic?

Key Concepts

pOH=0 | pOH=9 |
---|---|

Very Basic | Slightly Acidic |

**What is the relationship between H +] and pH?**

The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1). Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.

#### What equation shows the relationship between pH and pOH?

In order to calculate the pH, take the negative log of the hydronium ion concentration. To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.

**How do you know when to use pH or pOH?**

## Is a pOH of 14 acidic?

If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic….Steps for Problem Solving.

Steps for Problem Solving | |
---|---|

Plan the problem. | Need to use the expression pOH = 14 – pH |

Calculate. | Now substitute the known quantity into the equation and solve. pOH=14−4.42=9.58 |

**Is a pOH of 6 acidic?**

The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH of less than 7, while an acidic solution has a pOH of greater than 7.

### What is the relationship between the pOH and the OH ion concentration of a solution?

The pOH of a solution is the negative logarithm of the hydroxide-ion concentration.
