A salt containing an "unknown" anion is analyzed using the three Classification tests. Use the data to determine the identity of the anion. Test A-with barium and acid: the solution turns cloudy white and thickly opaque. Adding acid has no effect on the white substance. Test B-with acid: the solution remains clear and colorless like water. Test C-with silver and acid: the solution becomes slightly cloudy, like white thin fog. Adding acid removes the fog and the solution is colorless again. O s042503² O co₂2 O PO4³ O NOS O NO₂ O cr Oor Or
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
