Question
When a stronger affinity for this element is needed, the chelating agent EGTA is used instead of EDTA. Silicates of this element are sintered together to form the clinker used to make Portland cement. Palladium deposited on a compound of this metal makes up a Lindlar catalyst. This element produces an orange-red color in the flame test. Ions of magnesium and this metal are prevalent in hard water. Quicklime is the oxide of this element, while slaked lime is its hydroxide. This element’s sulfate makes up the mineral gypsum and its carbonate makes up limestone. For 10 points, name this alkaline earth metal found in teeth and bones. ■END■
