A titration process is done by using 0.2M of 20 ml of third analytical group main reagent solution with 0.1 M nitric acid solution if nitric acid is replaced by sulphuric acid of same concentration, then the volume of sulphuric acid equals ……

Half the volume of nitric acid
Double the volume of nitric acid
The volume of nitric acid
Quarter the volume of nitric acid

Answers

Answer 1

Sulfuric acid undergoes dissociation reaction to produce twice the amount

of hydrogen ions produced by nitric acid in solution.

The volume of sulfuric acid equals; Half the volume of nitric acid

Reasons:

The concentration of the analytical group = 0.2 M

Volume of reagent = 20 ml

Concentration of the nitric acid to be replaced = 0.1 M

Replacement for the nitric acid = Sulfuric acid

Concentration of the sulfuric acid = Concentration of the nitric acid = 0.1 M

Reaction = Titration

Solution:

Sulfuric acid in solution gives; H₂SO₄ (aq)  ⇄ 2H⁺ (aq) + SO₄²⁻(aq)

For nitric acid, we have; HNO₃ (aq) ⇄ H⁺(aq) + NO₃⁻(aq)

Therefore;

1 mole of sulfuric acid gives 2 moles of hydrogen ions

0.1 M solution of sulfuric acid gives 0.2 moles of hydrogen ions per liter

0.1 moles of hydrogen ions are therefore present in half a liter solution of 0.1 M sulfuric acid solution.

However;

0.1 M of nitric acid gives 0.1 moles of hydrogen ions per liter

Therefore;

The volume of sulfuric acid required = Half the volume of nitric acid

Calculate the mass of nitric acid required to make a 250mL solution with 2.40 ph

Please show steps, I am trying to learn!

Answers

The mass of nitric acid required to make the given solution is 0.0627 g.

The given parameters:

Volume of the acid, V = 250 mLpH of the acid, = 2.4

The hydrogen ion (H⁺) concentration of the nitric acid is calculated as follows;

[tex]H^+ = 10^{-pH}\\\\H^+ = 10^{-2.4}\\\\H^+ = 0.00398[/tex]

The molarity of the nitric acid is calculated as follows;

[tex]= 0.00398 \ H^+ \times \frac{1 \ M \ HNO_3}{1 \ H^+} \\\\= 0.00398 \ M[/tex]

The number of moles of the nitric acid is calculated as follows;

[tex]moles = M\times L\\\\moles = 0.00398\ M \ \times \ \frac{250 \ mL}{1000} \\\\moles = 9.95 \times 10^{-4} \ mol.[/tex]

The molar mass of nitric acid is calculated as;

[tex]HNO_3 = (1) \ + (14) \ + (16 \times 3) = 63 \ g/mol[/tex]

The mass of the nitric acid contained in the calculated number of moles is calculated as;

[tex]mass = moles\ \times \ molar \ mass\\\\mass = 9.95\times 10^{-4} \ mol. \ \times \ 63 \ g/mol\\\\mass = 0.0627 \ g[/tex]

Thus, the mass of nitric acid required to make the given solution is 0.0627 g.

A compound has a molar mass of 163.59 g/mol. If you have 736.155 grams of this compound, how many moles do you have?

Answers

Answer:

4.50000 moles

Explanation:

This is dimensional analysis. If there is 163.59 grams in 1 mole of this compound then the converse is true: in 1 mole of this compound there is 163.59 grams --> 1 mol/163.59 grams.

Now that you have your conversion factor:

736.155 grams * (1 mol/163.59 grams) is your equation.

When you multiply these together, grams cancel and you end up with the desired mole-based answer:

4.50000 moles (The extra zeros are to make up for the 6 significant figures in 736.155, feel free to omit them if necessary.)

the bradford assay only works at low protein concentrations

Answers

Answer:

Dilute the sample

Explanation:

The statement is not entirely accurate. The Bradford assay is commonly used to determine protein concentrations in a sample.

However, it is true that the Bradford assay is more accurate and reliable for measuring protein concentrations at low to moderate levels rather than at very high concentrations.

The Bradford assay is based on the binding of Coomassie Brilliant Blue dye to proteins. The dye undergoes a color change from brown to blue when bound to proteins, allowing for the measurement of protein concentrations. At low protein concentrations, the binding of the dye to proteins is well-calibrated and results in a linear relationship between protein concentration and color intensity, making it suitable for accurate quantification.

At high protein concentrations, the binding capacity of the dye may become saturated, leading to non-linear and less accurate measurements. The excess protein can also cause interference and affect color development. In such cases, dilution or alternative protein quantification methods may be more suitable, such as the BCA assay or the Lowry assay.

Therefore, while the Bradford assay can be used to measure protein concentrations across a range of concentrations, it is generally more reliable for low to moderate protein concentrations.

two samples of solids have similar reactivity with acids and similar densities. their masses and volumes, however, are not at all similar. is it possible that these are the same substance?

Answers

Given that the volume and mass of a substance are not defining properties, it is entirely possible for two samples with different volumes and mass to be the same substance.

What are defining properties of a substance?These are properties that can help us to identify a substance. The most useful of which tend to be chemical properties such as reactiveness or melting points. Colors and density can also offer the insight needed to identify elements and substances. Mass and volume are not properties of a substance given that they can change often depending on the sample size and thus do not help to identify a substance.

Therefore, since the volume and mass of a substance are not defining properties of a substance, we can confirm that it is entirely possible for two samples with different volumes and mass to be the same substance.
