A student analyzed an unknown sample that contained a single anion. The sample gave a yellow precipitated upon addition of a sol
kenny6666 [7]
<h3>Answer:</h3>

Anion present- Iodide ion (I⁻)

Net ionic equation- Ag⁺(aq) + I⁻(aq) → AgI(s)

<h3>Explanation:</h3>

In order to answer the question, we need to have an understanding of insoluble salts or precipitates formed by silver metal.

Additionally we need to know the color of the precipitates.

Some of insoluble salts of silver and their color include;

  • Silver chloride (AgCl) - white color
  • Silver bromide (AgBr)- Pale cream color
  • Silver Iodide (AgI) - Yellow color
  • Silver hydroxide (Ag(OH)- Brown color

With that information we can identify the precipitate of silver formed and identify the anion present in the sample.

  • The color of the precipitate formed upon addition of AgNO₃ is yellow, this means the precipitate formed was AgI.
  • Therefore, the anion that was present in the sample was iodide ion (I⁻).
  • Thus, the corresponding net ionic equation will be;

Ag⁺(aq) + I⁻(aq) → AgI(s)

What happens when you mix two different items (gases or liquids) together when they have different densities?
daser333 [38]

Answer:

Density measures how heavy something is for its size. Liquids of different densities can not be mixed and will separate with the heavier densities at the bottom and the lighter densities at the top. The different objects float at different levels in the liquid depending on their densities.
