Which of the following is an example of an autocatalytic reaction?
Reaction of chlorine gas with methane and carbon tetrachloride.
oxidation of a solution of oxalic acid by an acidified solution of potassium manganate (VII)
Oxidation of sulfur dioxide gas
Addition of calcium chloride to sodium phosphate
The concentrated acid is usually added to water and not the other way around because
When water is added to the acid it's temperature rises immediately and the acid starts boiling
Addition of water to sulfuric acid causes a highly endothermic reaction.
The acid, being less denser than water, stays above it.
Water has a higher heat capacity than the acid, and so water will absorb the heat
