Strong acid
= Strong acid
In <water>, a <strong acid> transfers its available <proton> essentially completely to <water> under the dilute conditions considered here. For the <pH> example, each initial <chemical acid> unit supplies one <hydronium> <ion>. “Strong” describes this conversion, rather than a high <concentration>. See <Chemistry 2e by Paul Flowers and others/14.3 Relative Strengths of Acids and Bases>.
