Question

An acid is a substance that increases the concentration of H3O+ ions in solution. Look at the reaction below of phenol (C6H5OH) with water: mc023-1.jpg Which reactant acts as an acid by contributing a H+ ion to create H3O+ in the chemical equation? C6H5OH(aq) H2O(l) C6H5O–(aq) H3O+(aq)

Answer 1

Answer is: phenol (C₆H₅OH).
Chemical reaction: C₆H₅OH(aq) + H₂O(l) → C₆H₅O⁻(aq) + H₃O⁺(aq).
As reactant phenol (C₆H₅OH) has neutral charge and as product of reaction has negative charge (1-), So in this chemical reaction phenol gives one proton (H⁺) to the water and water became hydronium ion (H₃O⁺).

Answer 2

i took the test so the answer A. C6H5OH
