Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

![On the basis of the general solubility rules given in the table, predict which of the following substances are likely to be soluble in water.
Simple Rules for the Solubility of Salts in Water
1. Most nitrate (NO3-) salts are soluble.
2. Most salts containing the alkali metal ions (Li*, Na*, K*, Cs*, Rb*), and the ammonium ion (NH4*) are soluble.
3. Most chloride, bromide, and iodide salts are soluble. Notable exceptions are salts containing the ions Ag*, Pb²+, and Hg,
2+
4. Most sulfate salts are soluble. Notable exceptions are BaSO4, PbSO4, Hg, SO4, and CaSO4.
5. Most hydroxides are only slightly soluble. The important soluble hydroxides are NaOH and KOH, The compounds Ba(OH)2, Sr(OH)2, and Ca(OH)2 are
marginally soluble.
6. Most sulfide ( S² ), carbonate (CO3² ), chromate (CrO4), and phosphate (PO4*) salts are only slightly soluble, except for those containing the cations in Rule
