All solutions are made up of two elements – a solute and a solvent. The solute is solid matter, liquid or gas, and the solvent is liquid into which the solute is mixed. Solubility is, to put it very simply, the amount of a particular...

The maximum amount of solute that can dissolve in a certain amount of solvent is know as solubility. The solubility of a solute is measured by the concentration of the solution - as more solute is being added, the solvent's concentration will increase, eventually becoming...

Substances in different phases of matter, namely, solid, liquid, and gas, have the property to dissolve in a liquid solvent to form a homogeneous solution (Henrickson, 2005). This property is called solubility. The extent to which the mass of a substance dissolves in the solvent...
Factors that affect solubility
By: Allan Taylor
The concept of solubility is of major importance in chemistry. Solubility is when a solid, liquid or gaseous substance (solute) dissolves in a liquid (solvent) to form a homogeneous solution. . The extent of the solubility of a substance in a solvent is measured as the...

Before one can talk about the factors that affect the solubility, one needs to to know what exactly "solubility" means. In several entries (Wikipedia, SolubilityofThings.com, About.com), solubility is defined as the following: the ability of a substance to dissolve. In the Wikipedia entry...

The property of solubility is generally thought of as the condition of molecular miscibility involving matter in liquid form. However, homogeneous solutions of solids and gasses also exhibit this property. For solubility to take place, a solute (solid liquid or gaseous element or compound) must...

It is true that there has been a dearth of exciting chemistry books for children in recent years. The latest chemistry book, published in 2010, and presented with a fun and educational angle, is the one by authors Simon Basher and Dan Green. It is...
How to write chemistry lab reports
By: Holly Rogers - 615383
A chemistry lab report must meet a range of criteria, which depends not only on the level of study/research you are at, but also on the topic you are writing about, and the audience it is targeting. All chemistry reports will start life in a...

Most children are aware of the form of snowflakes, delicate patterned lattices of regularly arranged crystals. They may also have watched the formation of ice ferns on glass windows in freezing weather. What they may not have realised is that these are the solid state...

Alum is a spice used for pickling, but has very little use as anything else. But here’s one use you and your kids will love: growing crystals at home. Ready? Here’s what you’ll need. Alum. Water. A bowl. A piece of cloth...
