TRANSITION METALS chemical reactions physical …
Transition metals are extremely useful metals on account of their physical or chemical properties eg lack of corrosion and greater strength compared to the Group 1 Alkali Metals. An alloy is a mixture of a metal with other elements (metals or non–metals). transition metals can be mixed together to make alloys to improve the metal''s properties to better suit a particular purpose.

Solubility and Complexation Equilibriums
At 25 C and pH 7.00, K sp for calcium phosphate is 2.07 × 10 −33, indiing that the concentrations of Ca 2+ and PO 4 3− ions in solution that are in equilibrium with solid calcium phosphate are very low. The values of K sp for some common salts are listed in Table 17.1 "Solubility Products for Selected Ionic Substances at 25 C"; they show that the magnitude of K sp varies dramatically
Sodium - Chemical properties | Britannica
17/8/2020· Sodium - Sodium - Chemical properties: Generally, elemental sodium is more reactive than lithium, and it reacts with water to form a strong base, sodium hydroxide (NaOH). Its chemistry is well explored. Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air. The corrosion of solid sodium by oxygen also is

Chemical Reactions of Oil, Fat and Fat Based Products
Reaction 6 will be alysed by transition metals and their complexes, which in this way act as prooxidants since the radicals produced in these reactions can start chains anew. Each new radical can start a chain responsible for many molecules of hydroperoxide, before a termination reaction stops it, and if there is air enough it will keep adding to the allylic positions.
