Ph key terms
WebbThe pH scale is the most common and trusted way to measure how acidic or basic a substance is. A pH scale measure can vary from 0 to 14, where 0 is the most acidic and 14 is the most basic a substance can be. Another way to check if a substance is acidic or basic is to use litmus paper. Webb28 mars 2024 · However, there is a pH counterpart called the pOH (the "power of the hydroxide ion"), which is defined as the negative logarithm of the hydroxide ion concentration: (15.8.2) p O H = − log [ O H −] For aqueous solutions at 25°C, the sum of the pH and pOH is always 14.00: (15.8.3) p H + p O H = 14.00

CH3COOH (aq) ⇌ H+ (aq) + CH3COO- (aq) Step 2: Write down the equilibrium expression to find Ka. Step 3: Simplify the expression. The ratio of H + to CH 3 COO - is 1:1. The concentration of H + and CH 3 COO - is, therefore, the same.
