It usually becomes a positive ion, or cation.
crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.
Sugar and salt are examples of products where crystallization does not only serve as separation/purification technique, but where it is also responsible for getting crystals with the right size (and shape) for further application of the products.

Answer:
Explanation:
You can infere the units of the rate constant for an <em>overall order 2 reaction </em>departing from the simplified case of a two identical reactants combined in a single elementary step:
- A + A → Products (single elementary step equation)
For that equation the differenttial form of the rate of reaction is:
- r = - d [A] / dt = K [A]²
The units of [A] are M¹ (i.e. M), and the units of - d [A] / dt are M¹ s⁻¹ . . . ( M stands for molar concentration)
Substituting the unis on both sides of the rate equation you get:
Solving for K:
- K = M¹ s⁻¹ M⁻² = M⁻¹ s⁻¹, which is the final result.
