Which of the following statements is INCORRECT?
All metals are equally reactive.
Silver is less reactive than sodium.
All metals are not equally reactive.
Potassium is more reactive than gold.
All metals are equally reactive.
Identify the scientifically false statement; chemical reactivity varies among metals, making the assertion that all are 'equally reactive' factually incorrect.
Identify the scientifically false statement; chemical reactivity varies among metals, making the assertion that all are 'equally reactive' factually incorrect.
Analyze the options based on chemical reactivity
Chemical reactivity of metals is determined by their position in the reactivity series. Some metals like potassium and sodium are highly reactive, while others like gold and silver are noble metals and have very low reactivity.
Evaluate the statements
The statement 'All metals are equally reactive' is scientifically false because reactivity is a variable property. The other statements ('Silver is less reactive than sodium', 'All metals are not equally reactive', 'Potassium is more reactive than gold') are all factually correct statements consistent with the reactivity series.
B: This is a scientifically correct fact. C: This is a correct observation that contradicts the idea of equal reactivity. D: Potassium is indeed higher than gold in the reactivity series, making this a correct statement.
A is correct because the statement 'All metals are equally reactive' is factually false as metals differ significantly in their chemical reactivity.
In questions asking for the 'INCORRECT' statement, immediately scan for absolute terms like 'all', 'always', or 'none', as these are frequent candidates for false statements.
