CHEM-C 243 Lecture Notes - Lecture 4: Chemical Equation, Lead, Strong Electrolyte
Document Summary
Activity series of metals: aid in predicting products of replacement reactions, most to least reactive elements. If a less active element tries to replace a more active element in a compound, no reaction will occur; on ap a reaction will always occur (to avoid memorization) Au lithium potassium strontium calcium sodium magnesium aluminum zinc chromium iron cadmium cobalt nickel tin lead. Hydrogen antimony arsenic bismuth copper mercury silver palladium platinum gold: notes to remember: Each element on the list replaces from a compound any of the elements below it; the larger the interval between elements, the more vigorous the reaction. Lithium-sodium are known as very active metals and they react with cold water to produce a hydroxide and hydrogen gas. Magnesium-chromium are considered active metals and will react with very hot water or steam to form an oxide and hydrogen gas. Oxides of the above metals resist reduction by hydrogen.
