    Acids
    Aqueous solutions of acids are electrolytes, meaning that they conduct an electrical current. ...
    Acids have a sour taste. ...
    Acids change the color of certain acid-base indicators. ...
    Acids react with active metals to yield hydrogen gas.
    Arrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, that acids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion (H+).
    The Brønsted-Lowry theory describes acid-base interactions in terms of proton transfer between chemical species. A Brønsted-Lowry acid is any species that can donate a proton, H+start text, H, end text, start superscript, plus, end superscript, and a base is any species that can accept a proton.
    A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct.
    Strong acid is an acid that ionizes completely in aqueous solution. It always loses a proton (H+) when dissolved in water. Weak acid is an acid that ionizes partially in a solution. ... Rate of reaction is faster for strong acids.
