What is acid?

The terms ACID (atomicity, consistency, isolation, and durability) refer to a set of characteristics of database transactions that are meant to ensure data validity despite errors, power outages, and other unforeseen circumstances.

For instance, a transfer of money between bank accounts, even when it involves many adjustments like debiting one account and crediting another, is only one transaction.

Building on previous work by Jim Gray, who identified atomicity, consistency, and durability but not isolation when describing the transaction concept, Andreas Reuter and Theo Härder created the acronym ACID in 1983.
