What is the driving force for the reaction of hcl(aq) and naoh(aq)?

vaieri [72.5K]

This is a type of metathesis reaction, also referred to as double-displacement reactions. In this reaction, the solvent and electrolyte is water, and they are driven by the formation of the non-electrolytic product. Therefore, the driving force behind the neutralization reaction between HCl and NaOH is the formation of sodium chloride, NaCl.

If the concentration of a saturated solution at 0∘C is 12.5 gCuSO4/100 g soln, what mass of CuSO4⋅5H2O would be obtained? [Hint:

Andrew [12]

Answer:

Mass of CuSO4.H2O obtained: $m_{total}=19.52 g$

Explanation:

The molecular weight of the salt is: $M=159.5 g/mol$

<u>In the solution</u>: 12.5 g of CuSO4

In moles: $n=\frac{12.5 g}{159.5 g/mol}=0.078 mol$

<u>Mass of wate</u>r:

5 moles of water per mol of salt: $m=\frac{5mol}{1mol}*0.078mol*\frac{18g}{mol}=7.02 g$

Mass of CuSO4.H2O obtained: $m_{total}=12.5 g + 7.02 g=19.52 g$

Analysis of the water content of a lake found in the desert showed that it contained 16.6 percent chloride ion, and had a densit

IRISSAK [1]

Answer : The molarity of the chloride ion in the water is, 5.75 M

Explanation :

As we are given that 16.6 % chloride ion that means 16.6 grams of chloride ion present 100 grams of solution.

First we have to calculate the volume of solution.

$\text{Volume of solution}=\frac{\text{Mass of solution}}{\text{Density of solution}}$

$\text{Volume of solution}=\frac{100g}{1.23g/mL}=81.3mL$

Now we have to calculate the molarity of chloride ion.

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

$\text{Molarity}=\frac{\text{Mass of chloride ion}\times 1000}{\text{Molar mass of chloride ion}\times \text{Volume of solution (in mL)}}$

Now put all the given values in this formula, we get:

$\text{Molarity}=\frac{16.6g\times 1000}{35.5g/mole\times 81.3mL}=5.75mole/L=5.75M$

Thus, the molarity of the chloride ion in the water is, 5.75 M
