Acids: H+ and Bases: OH-
There is a set of 5 nitrogenous bases used in the construction of nucleic acids.
Not necessarily. Acid is just used for very important research and experiments. And bases are used for bases. Sorry if I'm not helpful. :(
Volumetric cylinders are used in chemical laboratories to measure a specific amount of solutions, acids, bases...
Antacids are used to neutralize acids, and are therefore bases, so their pH values must lie between 7 and 14 on the pH scale.
'Polysaccarides' (in this question) should actually be 'amino acids'. Proteins are polymeric amino acids (20 different possibillities)
Amphoteric
Acids and bases are chemical substances that release ions when dissolved in water. Acids are compounds that release positive hydrogen ions in water. Bases release hydroxide ions, which are compounds made of an oxygen and a hydrogen. Acids and bases are used around the house for cleaning, but the levels of acids and bases in the body are also important. The body needs a neutral pH and controls the amounts of acids and bases through processes involving the kidneys, lungs and blood. Acids and bases are found in foods, the environment and in chemicals including pharmaceuticals. The pH levels in the blood are required to stay neutral, which is at a level of 7. When a dieter eats acidic foods, the body uses a buffering system to neutralize the positive ions released from the acids. Conversely, bases are also controlled to keep the body from becoming too alkaline.
Acids are used in many fields of industry and in homes.The sulfuric acid is used to make many products,paper,paints,etc. Like acids,bases have many uses.Sodium hydroxide is a base used to make soap and paper.
Acids form hydrogen ions (H+) that combine with water to form the hydronium ion (H3O+) and bases form hydroxide ions (OH-). To be exact: a hydrogen ion is an atom of hydrogen that has lost its electron. An acid is any substance that forms hydrogen ions in water. the hydroxide ion is polyatomic, made of oxygenand hydrogen. A base is any substance that forms hydroxide ions in water. The component ions of strong acids and bases completely dissociate.
When a base (or alkali, if you are english, like myself) is dissolved in water, hydroxide ions (OH-) are formed, this is what gives a base (or alkali) its reactive (and possibly corrosive) properties.
Acids eg vinegar
bases
Acids and Bases are used in basically everything. All cleaners are usually bases or weak acids, that help remove stains, by reacting with the substance. Some weak acids and bases are used in foods, for example vinegar is a base and citric acid (From lemons etc). is obviously an acid. Please respond if this did not fully help you understand acids and bases uses.
Acid base indicators are used to identify acids and bases. Among the common indicators are;PhenolphthaleinMethyl redMethyl orangeBromothymol blue

Both
Numbers are used. Numbers 1-6 are acids, number 7 is neutral, and numbers 8-14 are bases.
