This question tests your knowledge on; the properties of non-metal oxides in solution, the concept of equilibrium, pH.

Non-metal oxides such as (CO2, P4O10, SO2, etc) are acidic in solution. When l...

Cl- - 1s22s22p63s23p6

The 3p orbital is slightly unstable because of the single unpaired electron which is at a higher energy and wants to pair up, the 3p orbital is mor...

Because the weak acid is in excess, all of the strong base will react to form water and a salt of the acid. Since there is still some of the acid in the reaction mixture at the end point, an acidic buffer...

Mix the reagents and record the time taken for a specific observation, e.g. disappearance of colour which is characteristic for this chemical reaction. We repeat this step and add more manganese(II) ions;...

Even though simple covalent molecules consist of strong covalent bonds, these bonds are NOT broken when the substance is heated. Upon heating, the forces between the simple molecules (known as intermolecu...
