Buffer Solutions: Principle and Mechanism of their Action
Buffer solutions resist changes in pH. When a small amount of base or acid is added to a solution containing a buffer, it tries to [...]

Polar solvents are solvents with large dipole moments whereas nonpolar solvents have low or sometimes, no dipole moment at all. The dipole moment arises from [...]
Solutions are homogeneous mixtures through which light can pass, whereas suspensions are heterogeneous mixtures that cannot allow the light to pass through. The main difference [...]
Molarity and molality both measure the concentration of solutions. Molarity (M) is the measure of moles of solute per liter of solution. Whereas molality (m) [...]
A mixture is a blend of two or more substances when each of them has its own identification and properties. The resultant mixture can be [...]
Colligative properties are the properties that originate in solutions upon the addition of solutes. These are the physical changes dependent on the quantity of both [...]
Recrystallization is a separation technique used to separate compounds based on their different solubilities at different temperatures. Usually, recrystallization is used to separate compounds with [...]
Solvents are broadly classified into two types, polar and nonpolar solvents. Polar solvents are further divided into protic and aprotic solvents. Concisely, the difference between [...]
