A gas that has a volume of 13 liters, a temperature of 25 0C, and an unknown pressure has its volume increased to 27 liters and its temperature decreased to 15 0C. If I measure the pressure after the change to be 1.3 atm, what was the original pressure of the gas?

Answers

This is an exercise in the general or combined gas law.

To start solving this exercise, we obtain the data:

We use the following formula:

P₁V₁T₂ = P₂V₂T₁ ⇒ General Formula

Where

P₁ = Initial pressureV₁ = Initial volumeT₂ = Initial temperatureP₂ = Final pressureV₂ = Final volumeT₁ = Initial temperature

We clear the general formula for the final pressure.

An acid-base indicatior is a compound who's color is pH dependent. That is, it changes color depending upon whether it is in acid or base. This is because indicators are weak acids and undergo the following equilibrium. H-Ind ↔ H+1 + Ind-1 H-Ind = the indicator molecule that is protonated and predominates under acidic conditions. Ind-1 = the deprotonated indicator molecule (the conjugate base of the acid) and predominates under basic conditions. We are using the Acid-Base indicator, phenopthalein for this experiment. What is the color of this indicator in Acid? . What is the color of this indicator in Base

Answers

Phenolphthalein is pink in acid and colorles in base.

Substances called indicators are those whose solutions change colour as the pH changes. We refer to these as acid-base indicators. The conjugate base or acid versions of these typically weak acids or bases have various hues because of variations in their absorption spectra. When it comes into contact with an object that has a pH of 8.2, it turns pink. At a pH higher than that, it turns purple.

Additionally, ionisation, which modifies the charge and structure of the phenolphthalein molecule, is the cause of this shift in colour. If it comes into contact with an acid like vinegar or a neutral substance like water, it retains its colorlessness.

Therefore, Phenolphthalein is pink in acid and colorles in base.

Calculate the volume of 32% HCl required to make about 1 N HCl in 100ml volumetric flask

Answers

9.82 mL is the volume of 32% HCl required to make about 1 N HCl in 100ml volumetric flask.

What is Law of Equivalent ?

N₁V₁ = N₂V₂

where,

N₁ = Normality of solution with known concentration

V₁ = Volume of solution with known concentration

N₂ = Normality of solution with unknown concentration

V₂ = Volume of solution with unknown concentration

Now find the mass of solution

Mass = Density × Volume

         = 1.16 × 0.32 × 1000

Carbon monoxide and chlorine gas react to form phosgene:
If a reaction mixture initially contains 215 torr of CO and 245 torr of Cl2, what is the mole fraction of COCl2 when equilibrium is reached?

CO(g) + Cl2(g) ↔COCl2

KP= 310 atm at 700k

Answers

Carbon monoxide and chlorine gas react to form phosgene. If a reaction mixture initially contains 215 torr of CO and 245 torr of Cl₂. 0.76 is the mole fraction of COCl₂ when equilibrium is reached.

How to find Mole fraction ?

CO(g) + Cl₂ (g) → COCl₂ (g)           Kp = 310

With this reaction we can write the Kp expression

[tex]K_{p} = \frac{p_{COCl_2}}{p_{CO} \times p_{Cl_2}}[/tex]

We know that 1 atm = 760 torr

Now

[tex]p_{CO} = \frac{215 \times 1}{760}[/tex]

       = 0.28 atm

[tex]p_{Cl_2} = \frac{245 \times 1}{760}[/tex]

        = 0.32 atm

Now, we can write an ICE chart with pressures, so we can know the pressure of COCl₂.

        CO(g) + Cl₂ (g) → COCl₂ (g)           Kp = 310

I:        0.28     0.32          0

C:         -x         -x             +x
E:    0.28 - x  0.32 - x       x

Now put the value in Kp expression

[tex]K_{p} = \frac{p_{COCl_2}}{p_{CO} \times p_{Cl_2}}[/tex]

[tex]310 = \frac{x}{(0.28 - x) (0.32 - x)}[/tex]

[tex]310 = \frac{x}{0.0896 - 0.28x - 0.32x + x^2}[/tex]

310 (0.0896 - 0.28x - 0.32x + x²) = x

310 (0.0896 - 0.6 x + x²)  = x

27.776 - 186 x + 310 x² = x

310 x² -187 x + 27.776 = 0

By using the quadratic equation find the value of x:

[tex]x = \frac{b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

  [tex]= \frac{187 \pm \sqrt{(187)^2 - 4 \times 310 \times 27.776}}{2 \times 310}[/tex]

  [tex]= \frac{187 \pm \sqrt{34969 - 34,442.24}}{620}[/tex]

  [tex]= \frac{187 \pm \sqrt{526.76}}{620}[/tex]

  [tex]= \frac{187 \pm 22.95}{620}[/tex]

  [tex]= \frac{187 + 22.95}{620}\ \text{or}\ \frac{187 - 22.95}{620}[/tex]

  [tex]= \frac{209.95}{620}\ \text{or}\ \frac{164.05}{620}[/tex]

  [tex]= 0.33\ \text{or}\ 0.26[/tex]

Using the lowest value of x, we have that the partial pressure of COCl₂ would be 0.26 atm.

PpCO = 0.28 - x = 0.28 - 0.26 = 0.02

PpCl₂ = 0.32 - x = 0.32 - 0.26 = 0.06

[tex]X_{COCl_2} = \frac{P_{COCl_2}}{Pt}[/tex]

And Pt is the total pressure of all species in reaction so:

Pt = 0.02 + 0.06 + 0.26 =

    = 0.34 atm

The mole fraction:

[tex]X_{COCl_2} = \frac{0.26}{0.34}[/tex]

             = 0.76

Thus from the above conclusion we can say that Carbon monoxide and chlorine gas react to form phosgene. If a reaction mixture initially contains 215 torr of CO and 245 torr of Cl₂. 0.76 is the mole fraction of COCl₂ when equilibrium is reached.
