Are beverages usually acidic or basic? why is this?

ACIDIC

Explanation:

Usually beverages contain carbonated water. Carbonated water is the water containing dissolved carbon dioxide gas.

The carbon dioxide gas (CO₂) when dissolved in water produces carbonic acid (H₂CO₃), which makes the drinks acidic in nature.

H₂O(l) + CO₂(g) → H₂CO₃(aq)

This makes the pH of the drinks around 3 - 4.

Therefore, the beverages are usually acidic and not basic.

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.
