Do bases produce alkaline solutions
only when soluble
Define the bases
Metal oxides metal hydroxides Metal carbonates
Non-metal oxide + water =__________________
acidic solution (eg sulfur dioxide and carbon dioxide)
base + acid =
salt + water + (CO2) ^only when the base is a metal carbonate

What does a neutral solution have?
equal H and OH ions
