Substances

Substances

1. Solution

   • Liquids that have two types of substance.

2. Solvent

   • The substance in which the solute is dissolved.

3. Solute

   • Substance that is dissolved in a solution.

4. Concentration

   • Amount of a substance in a defined space. Is determined by the amount of solute and the volume of solution.

5. Standard solutions

   • Amount of concentration of an element or a substance that is precisely known.

6. Ppm

   • Stands for parts per million. Measuring unit can be written down as milligrams per liter (mg/L).

7. Dilution

   • Substance containing a reduced concentration of a solute in a solution. Done by mixing the solution with more solvent.

8. Stock solution

   • Concentrated solutions of known, accurate concentrations that will get diluted for laboratory use purposes.

9. Voliumetric analysis

   • Method of quantitative chemical analysis through which a substance gets determined by measuring the volume that’s occupied

10. Titration

    • Reaction of a solution with an unknown concentration and a solution with a known concentration.

11. Pipette

    • Glass tube used to move around liquids and to measure small quantities of liquid in a chemistry lab.

12. Conical flask

    • Glass container where the base is flat and round, and a cylindrical neck.

13. Burette

    • Tool used in chemistry to measure the volume of a liquid or a gas.

14. Equivalence point

    • Where all the acid has been neutralized by a base,

15. Indicator

    • When a substance gives a visible indicator that is usually a color change

16. End point

    • Point at which titration is completed., Marked by a change in color.
