(b) Acid-Base reaction: There is no change in oxidation number for any of the elements in this reaction—hence it is NOT an oxidation- reduction reaction. H2SO4 is an acid, and Zn(OH)2 acts as a base. (c) Oxidation-Reduction: Ca(s) has an oxidation number of 0, while Ca2+(aq) has an oxidation number of +2—hence Ca is being oxidized. 1. Write the nettonic equation for the following reaction: CaCl2(aq) + K2SO4(aq) → CaSO4(s) + 2KCl(aq) 2. What volume is needed dissolve 100.0g of NaBr to create a 0.20M solution?

Aqueous Reactions Provided by the Academic Center for Excellence 1 Reviewed June 2008 Aqueous Reactions Defining Aqueous Reactions Aqueous reactions are reactions that take place in water. To understand them, it is important to understand how compounds behave in water. Some compounds are electrolytes- they dissociate into separate ions in water.
Chemical Reactions and Equations is intended to help students to get accustomed to how a chemical reaction can be represented as an equation which will help us to understand the reaction effectively. NCERT solutions for class 10 science chapter 1 has been provided below to help you understand the subject more efficiently.

Solve: (a) The reactants contain Ba 2+, Cl–, K+, and SO 4 2-ions. If we exchange the anions, we will have BaSO 4 and KCl. According to Table 4.1, most compounds of SO 4 Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential.
