Acids are substances that provide hydrogen ions (H +) and lower pH, whereas bases provide hydroxide ions (OH –) and raise pH. … WebOct 25, 2024 · Acids that partially dissociate are weak acids, while acids that fully dissociate are strong acids. Explanation: The pH scale range from 0 to 14. A pH of 7 is neutral; below it is acidic while a pH above 7 is basic. While low pH might be an indication of a strong acid, a high pH on the pH scale indicates a base or alkaline. WebJan 30, 2024 · For strong acids, you can calculate the pH by simply taking the negative logarithm of its molarity as it completely dissociates into its conjugate base and hydronium. The same goes for strong bases, except the negative logarithm gives you the pOH as opposed to the pH. marxist approach in comparative politics
