The key difference between primary and secondary standard solution is that primary standard solution has a high purity and less reactivity whereas secondary solution has a less purity and high reactivity. ... Standard solutions have accurately known concentrations and we prepare these solutions using standard substances.

A simple standard is obtained by the dilution of a single element or a substance in a soluble solvent with which it reacts. A primary standard is a reagent that is extremely pure, stable, has no waters of hydration and has high molecular weight.

Basic solutions are made by dissolving the base, the solute, in a liquid solvent. Basic solutions are characterized by pH values higher than 7 and can conduct electricity. The qualitative properties of basic solutions include slippery textures and bitter flavors.

A true solution is where you can't differentiate between the solute and solvent molecules even at the microscopic level. It is completely homogeneous. ... An ideal solution, on the other hand, is one where molecular interactions between solute molecules are absolutely zero, and it follows Raoult's law.

A primary standard is some substance such as oxalic acid which can be precisely weighed out in pure form, so that the number of moles present can be accurately determined from the measured weight and the known molar mass. ... Secondary standards can also be prepared by titration against a primary standard solution.

A solution is a heterogeneous mixture of two or more substances. A solution is a homogeneous mixture of two or more substances. The solubility of most solids in water decreases as temperature increases. ... A dilute solution is one containing a large amount of solute relative to the amount of solvent.

Whereas a product has the potential of doing something, a solution is the application of a product to solve a specific industry need or business problem. Note the word specific. The other key concepts here are application and solve, from which the word solution is derived.

The only difference between an isotonic solution and an equilibrium is that an isotonic solution means that all the contents in the solution are balanced equally but there are movements while in an equilibrium, all the contents in the solution are also balanced equally but no movements are made.

Correct, standard form means that the terms are ordered from biggest exponent to lowest exponent. The leading coefficient is the coefficient of the first term in a polynomial in standard form. For example, 3x^4 + x^3 - 2x^2 + 7x.

Alkaline solution/compound is the same as a basic solution/compound. But you can specify "alkali" to refer to those bases that are soluble in water and that are salts of alkaline or alkaline earth metals too. A basic substance is usually one or two metal atoms bonded with an oxygen atom to make OXIDES.

A solution is a homogeneous mixture of two or more substance whose composition can be changed within certain fixed limits. ... True Solution. It is a homogeneous mixture having the size of its particles less than 1 nm . It's particles cannot be seen with naked eye or with microscope.
