Useful for CBSE, ICSE, All State Boards
Grade: 07
Subject: SCIENCE
Lesson : Acids, Bases and Salts
Acids are compounds that can donate H+ ions in water solutions.The role of water is essential in this definition. There are many different acids, but they all have something in common. They all have hydrogen attached to a nonmetal from either group 6A or group 7A. This last idea makes it easier to identify acids.
A base is a substance that can accept a hydrogen ion (H+) from another substance. A chemical can accept a proton if it has a negative charge, or if the molecule has an electronegative atom like oxygen, nitrogen, or chlorine that is rich in electrons. Like acids, some bases are strong and others are weak.
Salts, when placed in water, will often react with the water to produce H3O+ or OH-. This is known as a hydrolysis reaction. Based on how strong the ion acts as an acid or base, it will produce varying pH levels. When water and salts react, there are many possibilities due to the varying structures of salts
