According to the activity series, which of these metals will react with most acids to produce H2 gas? Cu,Na,Fe
Dear student,
The most reactive metals will react even with water while the least reactive will not react even with acid. According to reactivity series if we put the metals in order of their reactivity from most reactive to least reactive .
Since, In reactive series Na is above Cu and Fe.
Therefore, Sodium (Na) will react with most acids to produce hydrogen gas. Sodium is an extremely reactive metal and will react with most substances.
Please give a positive ratings to this answer.
And stay safe...
