What makes a substance a base? The pH scale: The pH scale is the scale used to measure whether a substance is acidic or basic. This largely depends on the number of hydrogen ions that the substance contains. The lower on the scale that a substance is, the more acidic it is, and the...
What is the difference between a strong acid and a weak acid? What makes a substance a base? What is an example of a strong acid? What the difference between strong acids and weak acids? Why does a strong acid have a weak conjugate base?
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...
Another major visible consequence of substance abuse is dental decay. “Meth mouth,” a term used to describe the extreme tooth decay seen in meth users, includes blackened, rotting, or missing teeth. This is due to dry mouth, bruxism (teeth grinding), poor hygiene, and acidic drug chemicals...
Piling up over time, masses of the botanical waste gradually turn into peat: a soggy, mud-colored substance. Peat can be used as animal bedding and as a fossil fuel, which makes it an important commodity in places like the Irish midlands. But to archaeologists, peat is a lot less ...
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 ...
What drink is most acidic? AGD spokesman Kenton Ross said thatRC Colawas found to be the most acidic soft drink studied, with a pH of 2.387 (the pH scale ranges from 0 to 14 for most liquids, with 0 being the most acidic and 14 being the least acidic—or most alkaline). ...
Anhydrous ammonia plays an important role in farming, especially as a nitrogen fertilizer. Nitrogen is a critical element for plant growth and development. It makes up one-sixth of amino acids, the building blocks of proteins, and chlorophyll (the compound responsible for photosynthesis). Anhydrous...
Property of a substance that causes it to donate protons or accept electrons during chemical reactions. The acidity of lemon juice makes it effective in household cleaning for removing scale. 3 Basicity Indicated by higher pH values, representing a higher concentration of hydroxide ions. Bleach has...
What makes a substance sour? Acids in food and drink create the sour taste sensation. 5 Are all acids sour? Not all acids have a sour taste; some are too weak or used in non-tasting contexts. 5 Is sourness a chemical property? Sourness is a taste perception related to the presence of...
