Generally, the Lewis definition of acids and bases is the most useful because it is the most inclusive of the three definitions. For example, the Brnsted-Lowry definition of an acid includes HF but not BH3, which doesn't lose a proton when attached by the lone pairs on a Lewis base. ...
Ionic equations, acids and bases 根据Bronsted-Lowry理论,酸(acid)是质子供体,碱(base)是质子受体。一些酸是双质子(diprotic),因此可以提供两个质子(比如硫酸)。有一些碱也是双质子,可以接受两个质子(比如碳酸根离子)。 可以使用指示剂...

But all bases are not soluble in water. If water is added to a concentrated acid, then the heat is generated. Mixing an acid or base with the water results into decrease in the concentration of ions (i.e. H3O+/OH–) per unit volume and the process is known as dilution....
Acids and bases are enormously important in enzyme chemistry. A thorough knowledge of acid–base chemistry is crucial to understand reaction mechanism and catalysis. According to the Bronsted (1923) definition of acids and bases, any substance (or a functional group) that has a tendency to lose ...
So, bases and acids work in sync to help our bodies function properly. Other uses Acids and bases are often used in science and technology. The batteries of cars and invertors contain a strong acid called sulphuric acid. Bases are used in manufacturing household cleaning products, baking soda...
