What is the concentration of chloride ion when 16.8ml of a 0.554 M solution of barium chloride is combined with 16.8ml of a 0.59
ozzi

Answer:

The concentration of chloride ion is 2.887 M.

Explanation:

Here we have a combination BaCl₂  and AlCl₃

1 mole BaCl₂ can produce 2 moles chloride ions as follows;

BaCl₂ → Ba²⁺ + 2Cl⁻

Therefore;

0.554  mole BaCl₂ can produce 2×0.554  moles chloride ions;

1 mole AlCl₃ can produce 3 moles chloride ions as follows;

AlCl₃ → Al³⁺ + 3Cl⁻

Therefore;

0.593 mole AlCl₃ can produce 3×0.593 moles chloride ions

Total concentration of chloride ions = 2×0.554 + 3×0.593 = 2.887 moles of Cl⁻ in 2×16.8 ml solution

The concentration of Cl⁻ is 2.887 M

13. Acid-catalyzed dehydration-condensation reactions of carboxylic acids and alcohols produce chemicals called
Sliva [168]

Answer:

A condensation reaction joins two larger molecules by splitting out a smaller molecule — usually water or ammonia — between them.

In an esterification reaction, an OH  from the acid and an H from the alcohol form a molecule of water.

The larger parts join to form the ester.

Ethanol and butanoic acid react to form ethyl butanoate.
