Q. What has a pH of 8 or higher?
What does it mean for a solution to be acidic or basic (alkaline)?
| pH Value | H+ Concentration Relative to Pure Water | Example |
|---|---|---|
| 6 | 10 | urine, milk |
| 7 | 1 | pure water |
| 8 | 0.1 | sea water, eggs |
| 9 | 0.01 | baking soda |
Q. Is a pH of 8 more basic or less basic than a pH of 6?
The pH scale ranges from 0 to 14 and indicates how acidic or basic a substance is. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.

Q. Does higher concentration mean higher pH?
The pH scale ranges from 0 to 14. High concentrations of hydrogen ions yield a low pH (acidic substances), whereas low levels of hydrogen ions result in a high pH (basic substances). The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1).
Q. Does pH increase with concentration?
If you add acid to a solution the concentration of hydrogen ions (acidity) increases and the pH decreases.
Q. What is the relation between pH and concentration?
As a solution gets more basic (higher [OH-]), the pH increases. As the pH of a solution decreases by one pH unit, the concentration of H+ increases by ten times. As the pH of a solution increases by one pH unit, the concentration of OH- increases by ten times….
| [H+] | [OH-] | pH |
|---|---|---|
| 1.0 × 10-14 | 1.0 | 14.00 |
Q. What happens when pH increases?
The logarithmic scale of pH means that as pH increases, the H+ concentration will decrease by a power of 10. This determination is due to the effect of hydrogen ions (H+) and hydroxyl ions (OH-) on pH. The higher the H+ concentration, the lower the pH, and the higher the OH- concentration, the higher the pH.
Q. What are the 10 most acidic foods?
- certain dairy products, including cheese.
- fish and seafood.
- high-sodium processed foods.
- fresh meats and processed meats, such as corned beef and turkey.
- certain starchy foods, such as brown rice, oat flakes, or granola.
- carbonated beverages, such as soda, seltzer, or spritzers.
Q. Is coffee high in acid?
Most coffee varieties are acidic, with an average pH value of 4.85 to 5.10 ( 2 ). Among the countless compounds in this beverage, the brewing process releases nine major acids that contribute to its unique flavor profile.
