Question
Which of the following is NOT used as a basis for arranging metals in the reactivity series ?AHow vigoroursly they react with dilute acid BHow vigoroursly they react with each other CHow easily their compounds are decomposed when heatedDHow easily they displace each other from their compounds
Solution
To determine which of the options is NOT used as a basis for arranging metals in the reactivity series, let's analyze each option:
A) How vigorously they react with dilute acid: This is commonly used as a basis for arranging metals in the reactivity series. Metals that react vigorously with dilute acid are placed higher in the series, indicating higher reactivity.
B) How vigorously they react with each other: This is also used as a basis for arranging metals in the reactivity series. Metals that react vigorously with each other are placed higher in the series, indicating higher reactivity.
C) How easily their compounds are decomposed when heated: This is another factor considered when arranging metals in the reactivity series. Metals whose compounds are easily decomposed when heated are placed higher in the series, indicating higher reactivity.
D) How easily they displace each other from their compounds: This is the correct answer. This factor is NOT used as a basis for arranging metals in the reactivity series. The reactivity series is based on how metals react with other substances, such as acids or oxygen, rather than how they displace each other from their compounds.
Therefore, the correct answer is D) How easily they displace each other from their compounds.
