WebApr 1, 2024 · The pH scale runs from 0 to 14, with 7 being a neutral pH. Anything higher than 7 is basic (or alkaline) and anything lower than 7 is acidic. The pH scale is an inverse of … WebJan 30, 2024 · In a sample of pure water, the hydronium concentration is \(1 \times 10^{-7}\) moles per liter (0.0000001 M) at room temperature. The equation to find the pH of a solution using its hydronium concentration is: \[pH = -\log {(H_3O^+)}\] Using this equation, we find the pH of pure water to be 7. This is considered to be neutral on the pH scale.

WebPure condensed water is neutral (pH 7). However, water in contact with air is slightly acidic (approximately pH 5.6) due to dissolved carbon dioxide ( C O X 2). Remarkably, the same applies to rainwater. Furthermore, water condensed from air is not pure.
