How many equivelants of a strong acid are required to neutralize 0.8 equivalent of a strong base?
I'm not having any luck finding how to do this in my textbook, If someone could explain it to me I could probably figure out the answer on my own, Thanks so much for your help. :)
Answer:
Because acids and bases have different numbers of hydrogen ions and hydroxide ions it is helpful if you expressed their concentrations in "equivalents". For example, sodium hydroxide has only one hydroxide ion but barium hydroxide has two so the "equivalent" amount of hydroxide ions from barium hydroxide would come from either half as much volume (same concentration) or half the concentration (same volume).
The answer to your question is 0.8 equivalents of a strong acid are required to neutralize 0.8 equivalents of a strong base.
depends which acid, which base, their composition, how long you allow the experiment to continue, if the container is open to the air, the temperature of the container, the reactants' pH value, the..
so many factors can contribute to this that if your textbook actually specified a dried and cut procedure, your teacher needs a new textbook
PS (sorry i could not help)
If you have 0.8 eq of a strong base then it will take that many equivalents of a strong acid to neutralize it. If you had 1 eq of a strong base then 1 eq of a strong acid is needed. If you had 10 eq of a strong base then 10 eq of a strong acid is needed. Hope this helps
Equivalent means the same so answer is 0.8 equiv strong acid -i.e. an equivalent amount . Note equivalents and moles are not the same if e.g. the acid has more than 1 replacable hydrogen like sulphuric with 2 then equivalent weight is 1/2 the molecular wt. & 3 replacable hydrogens as in phosphoric acid the equivalent wt. is 1/3 the molecular wt.
