Water, sugar and table salt are common examples of neutral substances. The pH scale rates substances based on how acidic or basic they are. A substance that is not acidic or basic is described as a neutral substance.Continue Reading
Acids and bases are the two extremes that are used to describe the chemical properties of any specific chemical. Acids taste sour, react strongly with metal and, if the acid is strong enough, can burn skin. Bases taste bitter, feel slippery and can also burn skin when strong enough. Mixing acids and bases, however, can neutralize the extreme effects of the substances.
The pH scale rates items on a scale of 0 to 14. Neutral substances are rated 7 on the scale. Substances with a pH below 7 are acidic, and those with a pH above 7 are basic. The lower the number, the stronger the acid is. The higher the number, the more basic the chemical is.
Pure water is a neutral substance, but other substances often mix with water and change its pH value. If an acidic substance like vinegar or lemon juice is added to the water, it will become acidic. If lye, ammonia or another basic substance is added to the water, the mixture becomes basic.Learn more about Acids & Bases
Soluble substances are those that easily dissolve in a solvent, such as water, and include sugar, salt, alcohol and some dishwashing detergents. In chemistry, solubility of a substance is a quantitative term that refers to the amount of substance that can dissolve in a given volume of a solvent. A substance is considered soluble if more than 0.1 gram of that substance can dissolve in 100 ml of solvent.Full Answer >
Succinic acid, or succinate, is used to make resins, lacquers and other coatings because its use improves the hardness and flexibility of these substances and shortens drying times compared to similar products that use petrochemicals. It is used in the manufacture of dyes, adhesives and sealants, in photography, in the manufacture of some polyesters, and to make the esters used in some perfumes.Full Answer >
There are numerous different kinds of acidic substances, like battery acid, concentrated sulfuric acid and lemon juice. These substances all have their own values of acidity, however, which is measured using the pH scale.Full Answer >
Some pH levels of common substances include a pH of 7.0 for pure water, a pH of 2.0 for lemon juice and a pH of 11.0 for ammonia. Human blood has a pH of 7.4, tomatoes have a pH of 6.6, and vinegar has a pH of 2.2.Full Answer >
