Remember two solutions of different concentrations are mixed together, the total amount of substance of the solution is the sum of the amounts of the individual solutions. when you get the sum of the amounts, you add their volumes and use those two to determine the new concentration of the solution.
A precipitation reaction is one in which dissolved substances react to form one (or more) solid products. Many reactions of this type involve the exchange of ions between ionic compounds in aqueous solution and are sometimes referred to as double displacement, double replacement, or metathesis reactions.
In this type of chemical reaction, we will predict what happens when solutions of two ionic compounds are mixed. If any reaction occurs, the two positive cations will exchange places. For example: ZnBr 2 (aq) + 2 AgNO 3 (aq) → Zn(NO 3) 2 + 2 AgBr. In this reaction we see that zinc and silver have switched places.
Sep 12, 2022 · If you have a collection of independent atoms, molecules, or ions, these particles will always exert forces of attraction and repulsion among themselves as they more closely approach each other.
A Rubidium hydroxide and cobalt(II) chloride are strong electrolytes, so when aqueous solutions of these compounds are mixed, the resulting solution initially contains Rb +, OH −, Co 2+, and Cl − ions. The possible products of an exchange reaction are rubidium chloride and cobalt(II) hydroxide):
Net Ionic. The objective of this section is to predict what will happen for single and double replacement reactions that occur in aqueous solutions. Note, if in a double displacement reaction two solutions combine and form a solid, you have a precipitation reaction.

If you remember from studying ionic bonding, the forces between the ions depends on the charge and the separation between the ions. These two ideas can be combined into one: charge density.
