Achemist uses 0.25 l of 2.00 m h2so4 to completely neutralize a 2.00 l of solution of naoh. the balanced chemical equation of the reaction is given below. 2naoh + h2so4 na2so4 + 2h2o what is the concentration of naoh that is used?

The molarity of the NaOH solution is 0.5 M.

Explanation:

Moles of in 0.25 L of 2.00 M solution:

Moles of = 2.00 mol/L × 0.25 L = 0.5 moles

Moles of in 2.00 L of an unknown Molarity :

1 mole gives 2 moles of ions.

Then 0.5 mole will give: 0.5 mol × 2 = 1.0 mol

1.0 mol of will neutralize the 1.0 mol of ions.

Moles of = Moles of = 1.0 moles

1 mol of are produced by 1 mol of NaOH

The 1 mole of will be produced from = 1 mol of NaOH

The molarity of the NaOH solution is 0.5 M.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
