A chemist uses a standard solution of 0.210 M lithium hydroxide (LiOH) to titrate 28.10 mL of sulfurous acid acid (H2SO3), she f

erik [133]

Answer:

0.0827M of H₂SO₃

Explanation:

LiOH reacts with H₂SO₃ to produce water and Li₂SO₃, thus:

2LiOH + H₂SO₃ → 2H₂O + Li₂SO₃

Where 2 moles of lithium hydroxide react with 1 mole of sulfurous acid.

As the chemist requires 22.14mL = 0.02214L of a 0.210M solution to neutralize the acid, moles of LiOH are:

0.02214L × (0.210mol / L) =0.004649 moles of LiOH.

As 2 moles of LiOH react with 1 mole of H₂SO₃, moles of H₂SO₃ are:

0.004649 moles of LiOH ₓ (1 mole H₂SO₃ / 2 mol LiOH) =

0.002325 moles of H₂SO₃

These moles are present in 28.10mL = 0.02810L. Thus, molar concentration of the acid is:

0.002325 moles H₂SO₃ / 0.02810L = 0.0827M of H₂SO₃

In a chemical equation, which symbol should be used to indicate that a substance is in solution?

lisov135 [29]

Example :

$2FeCl_3_{(aq)}+2KI_{(aq)}=2FeCl2_{(aq)}+2KCl_{(aq)}+I_2_{(s)}$

If you use the subscript (aq) (=aquaris) , this means that the substance is in a solution.

Subscripts:
-aq-this means that the substance is in a solution
-s-this means that the substance is a solid(or precipitate)
-l-this means that the substance is a liquid
-g-this means that the subtance is a gas
