An acid is a substance with a PH of less than 7. The pH scale measures how acidic or alkaline a substance is. A neutral substance such as pure water has a pH of 7! MY LATEST VIDEOS Acids form H+ ions in water.
Alkaline is a word you just don't see often. After all, acids can fairly be described asacidicwithout confusing anyone, but simply calling basesbasic, while true, isn't as helpful as it could be since "basic" has so many synonyms. The word "alkaline" is synonymous in chemistry with the...
There are many high-tech devices that are used to measure pH in laboratories. One easy way that you can measure pH is with a strip oflitmus paper. When you touch a strip of litmus paper to something, the paper changes color depending on whether the substance is acidic or basic. If the...

When the pH is below 7 , it is an acidic substance. The pH is a logarithmic factor, when a solution becomes ten times more acidic, the pH will fall by one unit. When a solution becomes a hundred times more acidic the pH will fall by two units. ...
The latter needs to be developed in its own right, and students need to be taught to think, not just in “pure” terms (e.g. of whether a substance is “ionic”, “covalent, or “metallic”), but also in applied (e.g. of whether a substance is cheap or expensive). They also ...
may affect the soil pH, which determines its acidity or alkalinity. The ammonia combines with the acidity of soil and neutralizes it, helping to keep pH levels at an optimum for plant growth. This is especially important because most crops grow best in soil that's slightly acidic to neutral...
