Calculate the mass of water in grams that could be produced from the reaction of 10.00mL 0.4122M hydrochloric acid and 35.00mL 0.1738M sodium hydroxide solution. Identify the limiting reactant.

To calculate the mass of water produced and identify the limiting reactant, we need to use the stoichiometry of the balanced chemical equation. The balanced chemical equation for the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) is:

HCl + NaOH → H2O + NaCl

Step 1: Calculate the moles of HCl and NaOH.
To do this, we will use the equation:

moles = concentration (M) × volume (L)

For hydrochloric acid (HCl):
moles of HCl = concentration of HCl × volume of HCl
moles of HCl = 0.4122 M × 0.01000 L
moles of HCl = 0.004122 moles

For sodium hydroxide (NaOH):
moles of NaOH = concentration of NaOH × volume of NaOH
moles of NaOH = 0.1738 M × 0.03500 L
moles of NaOH = 0.006083 moles

Step 2: Determine the stoichiometry of the reaction.
From the balanced chemical equation, we can see that the mole ratio between HCl and H2O is 1:1. This means that for every 1 mole of HCl reacted, we will get 1 mole of water.

Step 3: Identify the limiting reactant.
The limiting reactant is the reactant that is completely consumed or used up, thus limiting the amount of product formed. To identify the limiting reactant, we compare the moles of each reactant from step 1, using the stoichiometry from step 2.

For HCl, we have 0.004122 moles.
For NaOH, we have 0.006083 moles.

Since the mole ratio between HCl and NaOH is 1:1, it is clear that HCl is the limiting reactant because it has fewer moles than NaOH.

Step 4: Calculate the mass of water produced.
Since the stoichiometry ratio between HCl and water is 1:1, the moles of water produced will also be 0.004122 moles.

To calculate the mass of water, we will use the formula:

mass = moles × molar mass

The molar mass of water (H2O) is approximately 18.015 g/mol.

mass of water = 0.004122 moles × 18.015 g/mol
mass of water = 0.0743 g

Therefore, the mass of water produced from the reaction is approximately 0.0743 grams.

Summary: The limiting reactant in this reaction is hydrochloric acid (HCl). The mass of water produced is approximately 0.0743 grams.
