What is the uses of standard solution?
Standard solutions are solutions with a known concentration of a substance. They’re used in chemistry, particularly analytical chemistry, to help identify or determine the concentration of unknown substances.
What are the advantages of using standard solutions?
1. The error due to weighing the solute can be minimised by using concentrated stock solution that requires large quantities of solute. 2. We can prepare working standards of different concentrations by diluting the stock solution which is more efficient since consistency is maintained.
How are standard solutions used in titrations?
You use a standard solution to determine the concentration of the analyte during a titration. A standard solution is a solution containing a precisely known concentration of a primary standard. A primary standard should be a solid with a known formula and a purity of 99.98 \%.
What are the uses of solution in our daily life?
Examples of Solutions in Everyday Life
- antifreeze – The substance that keeps a car’s radiator from freezing up during the winter is a solution of water and ethylene glycol.
- mouthwash – The minty liquid that keeps your breath smelling fresh is one or more chemicals, such as cetylpyridinium chloride, dissolved in water.
What is a standard solution Class 12?
In analytical chemistry, a standard solution is a solution containing a precisely known concentration of an element or a substance.
How standard solution is prepared?
A standard solution can be prepared by weighing method in the following way. (a) The mass of solute needed is calculated and weighed. (b) The solute is dissolved in some distilled water in a beaker. (c) The solution is transferred into a volumetric flask.
What is one of the benefits of using stock solution?
Stock solutions are used to save preparation time, conserve materials, reduce storage space, and improve the accuracy with which working lower concentration solutions are prepared.
What are the types of standard solution?
There are two types of standard solutions known as primary solution and secondary solution.
Why is standardization of NaOH important?
The reason we must standardize strong base solutions is because substances like NaOH will naturally absorb moisture from the air and react with gases in the air, such as CO2, to produce unwanted impurities in the stock sample of the base.
What is the most important apparatus needed to prepare standard solution?
It is often necessary to have a solution with a concentration that is very precisely known. Solutions containing a precise mass of solute in a precise volume of solution are called stock (or standard) solutions. To prepare a standard solution, a piece of lab equipment called a volumetric flask should be used.
What are solutions used for in chemistry?
In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
What is meant by standard solution?
In analytical chemistry, a standard solution is a solution containing an accurately known concentration of an element or a substance, A known weight of solute is dissolved to make a specific volume. →Standard solutions are used to determine the concentrations of other substances, such as solutions in titration.
What are the characteristics of standard solutions?
A standard solution is any chemical solution which has a precisely known concentration . Similarly, a solution of known concentration has been standardized. To prepare a standard solution, a known mass of solute is dissolved and the solution is diluted to a precise volume.
What are some types of standard solutions?
Types of Solutions Define Solution. For example, salt and sugar is a good illustration of a solution. Different Types of Solutions. Depending upon the dissolution of the solute in the solvent, solutions can be categorized into supersaturated solution, unsaturated and saturated solutions. Recommended Videos Mixtures. Homogenous and Heterogeneous Solutions.
What is the characteristic of a solution?
Characteristics. A solution is a homogeneous mixture of two or more substances. The particles of solute in a solution cannot be seen by the naked eye. A solution does not allow beams of light to scatter.
