Swimming pool phh check calculations of ph and acid molarity. you notice that the water in your friend's swimming pool is cloudy and that the pool walls are discolored at the water line. a quick analysis reveals that the ph of the water is 8.00 when it should b 7.20 the pool is 5.00 m wide, 15.0 m long, and has an average depth of 1.50m. what is the minimum (in the absence of any buffering capacity) volume (ml) of 8.00 wt% h2so4 (sg-1.052) that should be added to return the pool to the desired ph? o ml the tolerance is +/-2% 98.1

3,48 mL of 8,00wt% H₂SO₄

Explanation:

The equilibrium in water is:

H₂O (l) ⇄ H⁺ (aq) + OH⁻ (aq)

The initial concentration of [H⁺] is 10⁻⁸ M and final desired concentration is [H⁺] =

Thus, you need to add:

[H⁺] = = 5,31x10⁻⁸ M

The total volume of the pool is:

5,00 m × 15,0 m ×1,50 m = 112,5 m³ ≡ 112500 L

Thus, moles of H⁺ you need to add are:

5,31x10⁻⁸ M × 112500 L = 5,97x10⁻³ moles of H⁺

These moles comes from

H₂SO₄ → 2H⁺ +SO₄²⁻

Thus:

5,97x10⁻³ moles of H⁺ × = 2,99x10⁻³ moles of H₂SO₄

These moles comes from:

2,99x10⁻³ moles of H₂SO₄ × × × = 3,48 mL of 8,00wt% H₂SO₄

I hope it helps!

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
