Chemistry in Everyday Life Chemistry in Everyday Life Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat‚ the air you breathe‚ your soap‚ your emotions and literally every object you can see or touch. Here’s a look at some everyday chemistry. Elements in the Human Body Your body is made up of chemical compounds‚ which are combinations of elements. While you probably know your body is mostly water‚ which is hydrogen and oxygen. Most of the human

loosely held ions which are to be exchanged with other ions in solutions which come in contact with them. These exchanges take place without any physical alterations to be the ion exchange material. Ion exchangers are insoluble acids or bases which have salts which are insoluble‚ and this enables them to exchange either positively charged ions (cations exchanges) r negatively charged one (anion exchangers). Many natural substances such as proteins‚ cellulose‚ living cells and soil particles exhibit ion

Epsom salt (sometimes called soaking salt) is a home remedy that has been used for tired muscles and aching joints for generations. It is inexpensive and easily found in many drug stores and even some grocery stores. Epsom salt is a naturally occurring mineral called magnesium sulfate. When you mix the correct amount (follow the instructions on the manufacturer’s label) into a warm bath and then soak for approximately 12 - 15 minutes‚ there are several health benefits. Soaking in a magnesium sulfate

Chemistry Revision F331 Isotopes - atoms with the same atomic number‚ but different mass numbers 131I - radioactive tracer for thyroid. 99Tc for tumours. Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial

Toxicological Chemistry - relates the aspects of toxicology to the chemical structure and reactivity of the toxin. It is concerned with the chemical interaction of the toxin with the receptor that gives the physiological response. The ultimate aim is to relate functional group chemistry of both toxin and receptor to the interaction Toxicity - the degree to which a substance causes damage to an organism Acute toxicity - the adverse effects resulting from a single exposure‚ or exposure over
