And while their experiments were real‚ the Boiling Frog Syndrome developed into a widespread didactic anecdote of subordinating‚ ignoring or neglecting the appearance of innocuous environmental phenomena leading to subsequent peril. Strictly speaking‚ it considers a cautionary tale about falling prey

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

It is important because it is essential to the health of human beings and of animals. for domestic use it is fined down to what is known as table-salt‚ and small quantities of other chemicals are added to it to keep it free-flowing when in contact with the atmosphere. Salt and potassium are combined to produce iodised salt‚ used when iodine is lacking in diet. It’s absence cause goitre‚ the swelling of the thyroid gland.
