1. The Tyndall Effect is most useful for distinguishing between: *
Yuki888 [10]

Answer:

a colloid and a solution

Explanation:

When solute particles completely dissolve in a solvent, a true solution is formed. The solute particles in this case are so little that they can not be seen with naked eyes. A true solution does not scatter rays of light.

In a false solution, the solute particles are larger than the solute particles in true solutions but are not large enough to be seen with naked eyes. False solutions scatter rays of light. False solutions are also called colloids.

The major difference between a solution and a colloid is that colloids scatter light rays (Tyndall effect) while a true solution does not scatter light rays.

Equal volumes of 0.2 M ammonia and 0.2 M nitric acid, HNO₃, are mixed. Write the net ionic equation for the reaction and identif
Black_prince [1.1K]

Answer:

The net ionic equation is

H₃O⁺+NH₃ ↔ NH₄⁺+H₂O

Explanation:

To write the net ionic equation, we are required to dissociate the into ions all strong acids and strong bases

Hence, nitric acid which is a strong acid is dissociated as follows

HNO₃+H₂O → H₃O⁺ + NO₃⁻

in the above equation, the nitrate ion  NO₃⁻, is a spectator ion because it is only present and does not partake in the chemical reaction so it is left out of the net ionic equation equation

Also the it is required to keep together weak bases in the solution therefore  for NH₃ which is a weak base we have

NH₃ + H₃O⁺ → NH₄⁺ + H₂O

Hence, the net ionic equation becomes

H₃O⁺ (aq) + NH₃ ↔ NH₄⁺(aq) + H₂O (l)
