Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of colors depending on its pH level was

Should there be limits to genetic modification of food? Should there be limits to genetic modification of food? It may seem very attractive to be able to genetically modify crops‚ but at what cost? Giant transnational companies are carrying out a dangerous global experiment by introducing large numbers of genetically engineered food into our diet. Genetic manipulations can result in unanticipated harmful effects‚ and because genetically engineered foods are not tested sufficiently‚ this experiment
