Think of three ways you could safely distinguish between a strong acid and a strong base.

--Acid is the substance when dissolved in water, increases the concentration of H+ ions.

--Such compound whose chemical formula begins with H, for example HCl (Hydrochloric acid), H3BO3 (Boric acid), CH2O3 (Carbonic

acid). Although CH3COOH (Acetic acid) is an exception.

--Its less than 7.

--Bases are the proton acceptor.

--Such compounds whose chemical formula ends with OH, for example KOH (Potassium hydroxide), NaOH (Sodium hydroxide).

--Its greater than 7.

Explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
