Some Basic Concepts of Chemistry

A diluted or concentrated solution; this is a qualitative means of expressing the solution’s concentration. A dilute solution contains a small amount of solute, whereas a concentrated solution contains a big amount of solute. However, these are relative phrases that do not provide us with the solution’s quantitative concentration. Concentration It refers to the amount […]

The equilibrium constant for the maximum quantity of solid which can be dissolved in aqueous solution is called the solubility product. The equilibrium constant for a solid which dissolves in aqueous solution is known as the solubility product constant (Ksp). All of the rules for calculating equilibrium constants are still in effect. Once a reaction

It is in equilibrium with both the undissociated acid and its dissociation products in the solution that a weak acid partially dissociates, forming a weak acid-water solution. Consider the acid acetic acid. The substituent effects of a weak organic acid determine the strength of the acid. Aside from that, the strength of an inorganic acid

Henderson and Hasselbalch equations can be utilised to evaluate the pH of a buffer solution. The mathematical value of the acid separation constant, Ka of the acid, is predicted or known. The pH is measured for a specified focus value of acid, HA, and sodium chloride, MA of the associated base, A–. For instance, the

Buffer preparation is a common process in chemistry and biochemistry laboratories. A buffer solution is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid.  Buffer solutions are used to help maintain a stable pH value of another solution that is mixed with the buffer. The buffer

A buffer is a chemical agent that helps keep the pH of a solution approximately constant, even when acids or bases are added. Buffering is vital in living systems because it allows them to maintain homeostasis, or a relatively consistent internal environment. Buffering capacity is provided by small molecules like bicarbonate and phosphate, as well

A buffer is an aqueous solution made up of a weak acid and its salt (acid buffer) or a weak base and its salt (base buffer) (basic buffer).  When a tiny amount of strong acid or base is given to it, its pH varies very little, and it is thus used to keep a solution’s

A weak acid and its conjugate base are frequently found in a buffer solution. When H+ is given to a buffer, the conjugate base of the weak acid accepts a proton (H+), allowing the H+ to be “absorbed” before the pH of the solution drops sufficiently.  When OH– is injected, the weak acid donates a

An acid and a base are present in a buffer solution. This solution is made by taking a weak acid and mixing it with its conjugate base. Combining a weak base with its conjugate acid is another technique to make it. In buffer solutions, the usage of conjugate solutions is extremely crucial. To maintain a

Phosphine (IUPAC name: phosphane) is a colourless, combustible, and highly poisonous molecule with the chemical formula PH3, which is classified as a pnictogen hydride. However, because of the presence of substituted phosphine and phosphine in technical-grade samples, they have a strong rotting fish aroma that is extremely unpleasant to the nose and throat (P2H4). Because
