Which pair of substances cannot form a buffered aqueous solution?

Chemistry

WARRIOR [948]2 years ago
5 0

HNO3 and NaNO3 cannot form a buffered aqueous solution from the following options.

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it.

Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. In nature, there are many living systems that use buffering for pH regulation. For example, the bicarbonate buffering system is used to regulate the pH of bloodstream, and bicarbonate also acts as a buffer in the ocean.

Buffer solutions resist pH change because of a chemical equilibrium between the weak acid HA and its conjugate base A−:

HA ⇌ H⁺ + A⁻

Liquids have more kinetic energy in their particles compared to solids. this allows the particles to move more freely, hence why they are fluids


Liquids diffuse from a region of high concentration to a region of low concentration, until equilibrium is reached


When heat is applied the particles gain more kinetic energy so they now have enough energy to overcome the bonds holding them in the liquid. this means they can evaporate off

A ____________ is a physical combination of things that can be separated. mixture compound
Degger [83]

Answer:

mixture

Explanation:

A mixture is something that can be separated, while a compound is something that can be separated (unless by chemicals).

An example of a mixture would be trail mix. You can separate the components without using chemicals.

the Temperature of a sample of an ideal gas in a sealed 5.0 l container is raised from 27 oC to 77oC. If the initial pressure of
matrenka [14]
Answer:
              The pressure increases to 3.5 atm.

Solution:
                According to Gay-Lussac's Law, " At constant volume and mass the pressure of gas is directly proportional to the applied temperature".

For initial and final states of a gas the equation is,

                                           P₁ / T₁  =  P₂ / T₂
Solving for P₂,
                                           P₂  =  P₁ T₂ / T₁    ----- (1)

Data Given;
                   P₁  =  3 atm

                   T₁  =  27 °C + 273  =  300 K
 
                   T₂  =  77 °C + 273  =  350 K

Putting values in eq. 1,

                                           P₂  =  (3 atm × 350 K) ÷ 300 K

                                           P₂  =  3.5 atm
