Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Why does the dehydration of an alcohol more often use concentrated sulfuric acid, H2SO4H2SO4, as the acid catalyst rather than dilute hydrochloric acid, HCl? Select one or more: Hydrochloric acid is too small to effectively react with the alcohol in the reaction. The additional water solvent from a dilute solution could reverse the dehydration reaction. Only acids with more than one proton can complete the dehydration reaction. The presence of the chloride ion could result in a competing substitution reaction.
