The less soluble Mg (OH) 2 precipitates because of the common ion effect due to the OH− added by the dissolution of Ca (OH) 2: [7] Mg2+ + Ca (OH)2 → Mg (OH)2 + Ca2+ Uses [ edit]
WebThis results in a relatively low pH compared to that of strong bases. The pH of bases in aqueous solution ranges from greater than 7 (the pH of pure water) to 14 (though some bases have pH values greater than 14). The formula for pH is: pH = -log 10 [H +] Sometimes, however, it is more convenient to focus on the pOH of bases, rather than the pH.
