Chemical changes are also called chemical reactions.The chemical changes are permanent changes which can usually not be reversed to form the original substance. A lot of energy (in the form of heat, light, sound, etc.) is either absorbed or given out in chemical changes. Thus, the various ...
Any comprehensive account of reactions catalysed by acids and bases would cover a large proportion of organic chemistry and biochemistry, and would demand at least a whole book; in fact, two excellent books giving a general coverage of the subject have recently appeared. 1,2 This chapter will ...
Properties of Bases A base in chemistry has several distinct properties that separate it from acids and solutions with a neutral pH. The following list includes a few examples: Reaction with Acids: When mixed with acids, bases undergo a chemical reaction. The OH-and H+groups combine, and the...
For example, perchloric is a very dangerous acid used to make explosives, hydroiodic is used as a disinfectant in medical facilities, and hydrobromic is an important chemical reagent.What are Strong Acids and Bases? Acids and bases play a fundamental role in the functioning of organic life, ...
Some indicators can't identify acids or bases, but can only tell you the approximate pH of an acid or a base. For example, methyl orange only works at an acidic pH. It would be the same color above a certain pH (acidic) and also at neutral and alkaline values....
An acid is a chemical species that donatesprotonsorhydrogenionsand/or acceptselectrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and...

Q.1. How do you explain acids and bases? Ans:Acids are those chemical substances that have a sour taste. Acids change the colour of blue litmus to red. Bases are the chemical opposites of acids. Bases are those chemical substances that have a bitter taste. Bases change the colour of red...
Reaction of acids and bases Digestion There are several indicators that a chemical change/chemical reaction has occurred. These include: Heat or light are given off Precipitate (solids) may form Color change may occur A gas may form (often seen as bubbling) The types of reactions are: Combinat...
Amphoteric substances can act as acids by giving up their protons, or they can act as bases by accepting protons from other atoms. According to Bronsted-Lowry acid-base theory: An acid is any chemical species that is capable of transferring its proton {eq}H^+ {/eq} to other atoms. ...
