Webb6 maj 2024 · A neutral pH value (neither an acid nor a base) is 7. Substances with a pH greater than 7 up to 14 are considered bases. Chemicals with a pH lower than 7 down to 0 are considered acids. The closer the pH is to 0 or 14, the greater its acidity or basicity, respectively. Here's a list of the approximate pH of some common chemicals. Webb27 juli 2024 · Any liquid with a pH of 10 or more can cause burns depending on the tissue it touches and how long the tissue is exposed. Note that some liquids, such as milk of magnesia, are higher than pH 10 because they are meant to counteract stomach acidity. Take as directed. When pH drops below about 2.5, it is considered potentially dangerous.
