    Fizzy drink tablets and powder contain a solid acid (usually citric acid ) and sodi

    um hydrogencarbonate.

    When dissolved in water, the solid acid ionizes to form H+(aq) ions, which react

    with the sodium hydrogencarbonate.

    There is effervescence, carbon dioxide gas being given off

    Heat and water cause decomposition of hydrogencarbonate to produce carbon dioxide

    So, to prevent fizzy drink tablets become useless, it should be kept in cool dry place
