A fictional compound AX2 has a molar mass of 128.99 g/mol and a Ksp of 7.7989e-10. It dissociates in water based on the equation: AX2(s) ⇔ A2+(aq) + 2X-(aq) Based on this information, label the statements below as true or false. If more soluble A(NO3)2 is added to the system then [X-] will increase. If the solution is heated and the solubility decreases, then the heat of solution for AX2 is exothermic. If more solid AX2 is added to the system then [A2+] will increase. If soluble NaX is added to the system then [A2+] will increase. The mass solubility of AX2 is less than 1.50E-2 g/100mL H2O. The molar solubility of AX2 is less than 2.90E-4 mol/L. If more solid AX2 is added to the system then [X-] will decrease.
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.
Bronsted Lowry Base In Inorganic Chemistry
