The approximate pH of these solutions will be determined using acid-base indicators. 4- Procedure. You may need to consult your notes. The “pH” is always written with a lowercase “p” and an uppercase “H”, which stands for “power of hydrogen.” pH values are related to hydrogen ion (\(\ce{H^+}\)) concentrations. The substance is called basic when the pH number scale is from 7 until 14, and for acid, the substance is called acidic when the pH number scale is from 0 until 7. By continuing we’ll assume you’re on board with our cookie policy. Some acids dissociate only partly, releasing very small amounts of H+ ions, and are called weak acids. Also, we thougt vinegar was a base, but it came out as 2 so it was actually very acid. A. Pairs of students will  volunteer their responses in a whole-class discussion.
