What could the pool owner do to reduce the acidity of the pool?

Add a base  

Explanation:

Two of the acids that may cause high pool acidity are hydrochloric acid (HCl) and hypochlorous acid (HOCl).

To reduce the acidity in the pool, they must add a base to neutralize the excess acid.

A commonly used base is sodium carbonate — Na₂CO₃ or washing soda. The equations for the reactions are:

Na₂CO₃(aq) + 2HCl(aq) ⟶ 2NaCl(aq) + H₂CO₃(aq)

Na₂CO₃ (aq) + 2HOCl(aq) ⟶ 2NaOCl(aq) + H₂CO₃(aq)

The initially formed carbonic acid will decompose into carbon dioxide and water.

H₂CO₃(aq) ⇌ CO₂(aq) + H₂O(ℓ)

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

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.
