A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. After the addition of a small amount of strong acid or base, Its pH changes very little and thus it is used to prevent changes in the pH of a solution. Buffer solutions are used to maintain a constant pH in a wide variety of chemical applications. One example of a buffer solution found in nature is blood. Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO3-) to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death.

What is Glass Electrode?

Do you know, What is an electrode? and Types of it? Electrodes: An electrical conductor forming half cell of an electrochemical cell. An electrode is a conductor that is used to make contact with a nonmetallic part of a circuit. Usually, the metal is used as either of the two terminals of an electrically conducting medium It conducts current into and out of the medium, which may be an electrolytic solution as in a storage battery, or a solid, gas, or vacuum.

By using an Electrochemical cell, Fuel cell By using coal, natural gas, Biomass, nuclear fission reactions, sunlight, wind, and hydropower. Correct👍✔ Today we will discuss Electrochemical cell An electrochemical cell is a device that can generate electrical energy from the chemical energy through reactions occurring in it. electrical energy→ chemical energy Can you give an example of this type of cell?

The water that contains a high concentration of dissolved salts is called brackish water. Desalination is the process of removing common salts (mostly NaCl) from water Commonly used Membrane techniques for Desalination are - i) Electrodialysis ii) Reverse Osmosis About Electrodialysis we learnt already

Why there is a need for water treatment? As we know that water is present on the earth in large quantities. composed of the chemical elements hydrogen and oxygen. It exists in gaseous, liquid, and solid states. A tasteless and odourless liquid at room temperature. It has the important ability to dissolve many other substances. So there is a change in the properties of water. Sources of water include Rainwater, surface water, groundwater and frozen water.
