Some examples of acidic substances are. 1 Lemon. It consists of citric acid and is sour in taste. 2 Vinegar. This also consits of citric acid. Therefore sour in taste. 3 Apple. Have you ever wondered why some apples taste sour. They taste sour because they consist of Malic acid. These acids are not that dangerous. Dangerous acids are HCl and H2So4


Above seven means the substance is a base, or alkaline, substance. Battery acid is ranked as one of the most acidic substances because is has a pH value of zero. Concentrated sulfuric acid is also very acidic, being listed as one. Lemon juice and vinegar are also very acidic, but not as much so since they are ranked at a level two pH rating ...


Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic). Table 1 has examples of substances with different pH values (Decelles, 2002; Environment Canada, 2002; EPA, date unknown).


What Are Examples of Acids and Bases at Home? Common household substances that are acidic include coffee, battery acid, vinegar and lemon juice, while common household substances that are basic include drain cleaner, bleach, soap, ammonia, milk of magnesia and baking soda.

When reacted with metals, these substances produce hydrogen gas. Acids are sour-tasting substances. Examples: Sulfuric acid (H 2 SO 4), Hydrochloric acid (HCl), Acetic acid (CH 3 COOH). General Properties of Bases. They are found to have a soapy texture when touched. These substances release hydroxide ions (OH – ions) when dissolved in water.


Bakers use it in breads and cakes mixed with an acid, such as vinegar or lemon juice, to create carbon dioxide bubbles that cause their products to be lighter in texture. Baking powder contains baking soda and cream of tartar, a mild acid. When the two mix with liquids, they form the same gas bubbles. Ammonia is a highly caustic alkaline substance.


The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than ...


The word "alkali" is derived from Arabic al qalīy (or alkali), meaning the calcined ashes (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic.
