single arrow vs double arrow

Postby 205192823 » Sat Dec 07, 2019 1:45 pm

when the equation involves a weak acid it is written with a double arrow because the reaction is reversible but when the equation involves a strong base it is just a single arrow. HCl+H2O --> H3O+ + Cl-, if it was a weak acid that arrow would have one facing the product and the other facing the reaction. -->

Yes, double arrows typically indicate that the reaction does not completely dissociate and is reversible. Single arrows indicate that the reaction dissociates completely.
