Is zinc a basic radical or acid radical?​

depends on the element it's reacting with..

Explanation:

if the another element requires less energy to loose electron then zinc will become negatively charged and hence becomes acidic radical..

normally if it is reacting with element with valency 4 and Atomic number less than it(Ti,Si,C) then it will lose electron and gain positive sign and henve becomes basic radical..

we need the questions , i may then you.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
