Acid Rate of Reactions Investigation
The first 200 words of this essay...
This is any substance with a pH value less than 7, an example of a strong acid is hydrochloric acid as it has a pH of 1. The solution contains free roaming H+ ions. It usually contains hydrogen ions that dissolve in water to produce hydrogen ions but these do not exist on their own in the solution.
This again is any substance 3 with a pH value more than 7, an example of a strong alkali is sodium hydroxide as it has pH of 14. Alkalis contain OH- ions that also move around freely in the solution. It is a base normally of a hydroxide of a metal in group 1 or 2 of the periodic table, that is soluble in water and produces hydroxide ions (OH) in solution. These make a solution alkaline.
This is the reaction between an acid (hydrochloric acid) and a base (alkali) to produce a salt (sodium chloride) and water only. An equal amount of hydrogen and hydroxide ions react and form together to form a neutral solution.
