SALTS EVERYDAY First some words about salts in chemistry. Salts are ionic compounds that can result from the neutralization reaction of an acid and a base. They are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Salts can appear to be clear and transparent (sodium chloride)‚ opaque‚ and even metallic and lustrous (iron disulfide). In many cases the apparent opacity or transparency are

MATHS IN DAILY LIFE Mathematics is an integral part of our life. Right from the time we wake up in the morning till we go to sleep‚ invariably we are using mathematics in one or the other way. Teaching mathematics in classroom using pictures from daily life can help students in understanding a concept in a better manner. For instance‚ when a child is introduced the concept of 3 dimension‚ he/she is not able to visualize it. Learning of this concept can be made simpler and interesting by showing
