What is HCl state of matter?
HCl is a gas at normal temperature and pressure with a normal boiling point of -85 °C. The gas is generally referred to as hydrogen chloride, while the solution is more commonly referred to as hydrochloric acid, however the terms are often used interchangeably. HCl gas is readily absorbed by water.
Is NaCl liquid or aqueous?
A NaCl solution is an aqueous solution. A non-aqueous solution is a solution in which water is not the solvent. Examples of non-aqueous solutions are solutions used in dry cleaning (a solution of ethene in the solvent dichloromethane). A solid solution is a solution in which a solid is the solvent.
How do you make an aqueous solution?
Determine the mass in grams of one mole of solute, the molar mass, MMs. Decide volume of solution required, in liters, V. Decide molarity of solution required, M. Dissolve 93.52 g of NaCl in about 400 mL of distilled water, then add more water until final volume is 800 mL.
What is a basic aqueous solution?
A basic solution is an aqueous solution containing more OH-ions than H+ions. In other words, it is an aqueous solution with a pH greater than 7. Examples of common basic solutions include soap or detergent dissolved in water or solutions of sodium hydroxide, potassium hydroxide, or sodium carbonate.
What do you mean by aqueous solution?
Definition. An aqueous solution is one in which the solvent is liquid water. That is, solute (dissolved) ions and molecules are surrounded by water molecules and incorporated into the network of bonds within the water. The dissolved species then spread throughout the water.
Is Aqueous a state of matter?
Near absolute zero, a substance exists as a solid. In a chemical equation, the state of matter of the chemicals may be shown as (s) for solid, (l) for liquid, and (g) for gas. An aqueous solution is denoted (aq).
Which is an example of a non aqueous solution?
Common examples are liquid ammonia, liquid sulfur dioxide, sulfuryl chloride and sulfuryl chloride fluoride, phosphoryl chloride, dinitrogen tetroxide, antimony trichloride, bromine pentafluoride, hydrogen fluoride, pure sulfuric acid and other inorganic acids.
Why are non aqueous solvents important?
The most important nonaqueous solvents of this class are the lower alcohols methanol and ethanol. They resemble water in their acid–base properties but, because of their lower dielectric constants, facilitate processes producing ions to a much smaller extent.
What are the advantages of non aqueous solvent?
Advantages of Non-aqueous Titrations
- It is useful for the titrations of very weak acids or bases.
- Many organic acids which are not soluble in water, can be dissolved in non-aqueous solvents.
- It can be used for titration of mixture of acids as well.
- These titrations show sharp end point with internal indicator.
Is used as titrant in non aqueous titration?
2) Titrant used in the titration of weak acids: Ex:-sodium methoxide, lithium methoxide, potasium methoxide , tetrabutyl ammonium hydroxide etc.
Why is mercuric acetate used in non aqueous titration?
Addition of mercuric acetate ( which is undissociated in acetic acid solution ) to halide salt replaces the halide ion by an equivalent quantity of acetate ion, which is a strong base in acetic acid.
How do you make a mercuric acetate solution?
Mercuric Acetate TS —Dissolve 6.0 g of mercuric acetate in glacial acetic acid to make 100 mL. Store in tight containers, protected from direct sunlight. Mercuric–Ammonium Thiocyanate TS —Dissolve 30 g of ammonium thiocyanate and 27 g of mercuric chloride in water to make 1000 mL.
Why is acetic anhydride used in non-aqueous titration?
Another important feature of acetic anhydride as a co-solvent (or reagent) for the titration of pharmaceutical compounds is that it enables the direct non-aqueous titration of halide salts (mainly hydrochlorides) of organic bases and quaternary ammonium salt-type drugs.
