Aspirin or other over-the-counter analgesics are widely recognized as effective for the treatment of tension headache. Aqueous solution of a salt is indicated by placing the letters aq in round brackets, aqto the right of the formula for the ionic compound. It belongs to the homologous series of organic molecules called carboxylic acids.

The 'opposite' of an acid is a base, and a soluble base is called an alkali. Antacid indigestion tablets are mild alkalis that react by neutralising excess stomach acid which is the 'strong' hydrochloric acid which your delicate stomach lining and upper gut can only take so much of. To enhance the appeal of food.

Detergents help remove dirt from the surface of materials in combination with water. So all of this is still pretty important chemistry even for the 21st century, with strong links to agriculture, the environment and leading a stressful life. Instead they are degraded to the metabolically inert uric acid which is then excreted from the body.


Topic 18 is the additional HL material for Topic 9. Smaller doses are based on these standards, e. Carboxylic acids have some direct uses but they are usually converted into a more useful chemical form e. They may alter incoming sensory sensations, alter mood or emotional state, alter physiological state, alter state of consciousness, activity level or coordination.

Citrus fruits such as lemons, grapefruit, oranges, and limes have citric acid in the juice. In the study, all athletes were male and were highly skilled in taekwondo.

While inosine can serve a similar function as the degeneracy "D", it is an actual nucleotide, rather than a representation of a mix of nucleotides that covers each possible pairing needed. In acute poisoning, a single large dose is taken; in chronic poisoning, higher than normal doses are taken over a period of time.

Ethanol is the starting point for the manufacture of other organic chemicals e. These are important agri—chemical fertilisers supplying nitrogen to the soil for better plant growth. Industrial uses include all electrolysis processes like aluminium extraction from molten aluminium oxide purified bauxite orepurifying copper using copper electrodes and copper II sulphate solution.

Uric acid is a C 5 H 4 N 4 O 3 (7,9-dihydro-1H-purine-2,6,8(3H)-trione) heterocyclic organic compound with a molecular weight of Da.

Many enzymes are involved in the conversion of the two purine nucleic acids, adenine and guanine, to uric acid. Initially, adenosine monophosphate (AMP) is converted to inosine via two different mechanisms; either first removing an amino group by deaminase to.

Acids, Bases & Salts are very important chapter in GCE O Levels Chemistry (IB Chemistry and IP Chemistry). In fact, there are considered heavy-weightage topics (in terms of marks as well as content) that are related to many other chemistry topics.

IB Chemistry Topic 8 Acids and bases • The characteristics of the pH curves produced by the different combinations of strong and weak acids and bases.

• An acid–base indicator is a weak acid or a weak base where the components of the conjugate acid–base pair have different colours. These are based of IB Chemistry exam past paper. A number sign (#) is used with this entry because maple syrup urine disease (MSUD) can be caused by homozygous or compound heterozygous mutation in at least 3 genes: BCKDHA on chromosome 19q13, BCKDHB on chromosome 6q14, and DBT on chromosome 1pThese genes encode 2 of the catalytic components of the branched-chain alpha-keto acid dehydrogenase complex (BCKDC), which.

IB Chemistry revision notes on acids and bases (sl) In Bronsted Lowry theory an acid is any species that can release a hydrogen ion. Bases become any species that can accept a hydrogen ion.

An Arrhenius acid is, of course, also a Bronsted Lowry acid, but the reverse is not necesarily true.
