Answer:
Yes
Explanation:
Let's write the reaction as
CV⁺+ OH⁻ ⟶ CVOH
The reaction is first order in [CV⁺] and in [OH⁻], so the rate law is
rate = k[CV⁺][OH⁻]
A bimolecular collision between a crystal violet ion and a hydroxide ion as an elementary step would predict the observed rate law.
However, other plausible mechanisms may predict the same rate law.
Potassium and Nitrate ions are spectator ions in the reaction:

<h3>What are spectator ions?</h3>
Ions that are not involved in the actual chemical reaction are called spectator ions.
A precipitation reaction occurs when two ionic compounds react to produce a precipitate and an insoluble substance which stays in the solution as a spectator ion.
Hence, Potassium and Nitrate ions are spectator ions in the reaction:

Answer:
Two different changes have occurred in the beaker. The description of the step 1 suggests that most likely a <u>chemical change</u> has occured while the description of the step 2 correspond to a<u> physical change</u>.
Explanation:
When the mixture of two liquid colorless substances results in the appearance of solid particles you first thing in the appareance of a new substance. If this is the case, it means that the original substances reacted chemically to form a new product, so this is a chemical change.
On the other hand, the second step describes just a physical change as it has been just that the yellow particles settled and then a physical separation by <em>decantation</em>. Decantation does not change the chemical properties of the particles settled, they are jsut separeated from the liquid. During this step both the yellow particles and the liquid in the beaker keep their chemical properties, so this is just a physical change.
