Ph of 3.5
WebJul 30, 2024 · Orange juice is mildly acidic (pH = approximately 3.5), whereas baking soda is basic (pH = 9.0). Acids are substances that provide hydrogen ions (H +) and lower pH, whereas bases provide hydroxide ions (OH –) and raise pH. The stronger the acid, the more readily it donates H +. WebHowever, recall that pH calculations are on the logarithmic scale and thus, large differences are made to appear small. The hydrogen ion concentration of "Solution 1" is calculated to be, [H + ] = 10 −3.5 ≈ 0.00032 = 3.2 × 10 −4 M, and the hydrogen ion concentration of "Solution 2" is calculated to be, [H +] = 10 −3.8 ≈ 0.00016 = 1.6 ...
