Class 12th Chemistry
- Solutions 1. What is the pH of 0.1 M solution of sodium acetate? The pH of a 0.1 M solution of sodium acetate is 4.75. Notes 1. Atomic Structure: • Atomic structure is the study of the components of an atom and its organization. • It includes the protons, neutrons, electrons and the force that binds them together. • It also involves the study of the various subatomic particles and their properties. 2. Chemical Bonding: • Chemical bonding is the force that holds atoms and molecules together. • It is the result of the attraction between the positively charged nucleus of one atom and the negatively charged electrons of another atom. • Types of chemical bonds include covalent, ionic, hydrogen and metallic. 3. Chemical Reactions: • Chemical reactions are processes that involve the breaking and forming of bonds between atoms. • They can result in the creation of new substances or the transformation of existing substances. • Reactions occur when the energy of the reactants is greater than the energy of the products. 4. Chemical Equilibrium: • Chemical equilibrium is the state in which the concentrations of reactants and products remain constant over time. • It occurs when the forward and reverse reactions occur at the same rate. • Equilibrium can be affected by changes in temperature, pressure or the concentration of reactants or products. 5. Solutions and Colloids: • Solutions are homogeneous mixtures of two or more substances. • Colloids are mixtures of two or more substances in which one substance is dispersed in the other. • Solutions and colloids can be classified as either gaseous, liquid or solid.
