Aqueous hydrochloric acid hcl reacts with solid sodium hydroxide naoh to produce aqueous sodium chloride nacl and liquid water h2o. what is the theoretical yield of water formed from the reaction of 1.1g of hydrochloric acid and 2.1g of sodium hydroxide?

Answer : The theoretical yield of water formed from the reaction is 0.54 grams.

Solution : Given,

Mass of HCl = 1.1 g

Mass of NaOH = 2.1 g

Molar mass of HCl = 36.5 g/mole

Molar mass of NaOH = 40 g/mole

Molar mass of = 18 g/mole

First we have to calculate the moles of HCl and NaOH.

Now we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of HCl react with 1 mole of NaOH

So, 0.030 mole of HCl react with 0.030 mole of NaOH

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of

From the reaction, we conclude that

As, 1 mole of react to give 1 mole of

So, 0.030 moles of react to give 0.030 moles of

Now we have to calculate the mass of

Therefore, the theoretical yield of water formed from the reaction is 0.54 grams.
