An acid is a substance that increases the concentration of h3o+ ions in solution. look at the reaction below of phenol (c6h5oh) with water: which reactant acts as an acid by contributing a h+ ion to create h3o+ in the chemical equation?
a. c6h5oh(aq)
b. h2o(l)
c. c6h5o–(aq)
d. h3o+(aq)

Option (a) is the correct answer.

Explanation:

The reaction will be as follows.

Here, phenol is acting as an acid as it's conjugate base is more stabilized due to resonance. Whereas if ion is donated by water molecule then it will give a hydroxide ion which is not a strong base.

Therefore, here phenol is acting as an acid as it is donating an ion.

yes it is balanced

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
