(a). What happens when zinc granules are heated with sodium hydroxide solution? Write equation of the reaction which takes place. (b). What happens when bases react with non-metal oxides? Explain with the help of an example. What does this reaction tell us about the natrue of non-metal...
The compounds are formed by a reaction of a metal, a hydroxide of an alkali metal, and hydrofluoric acid or boric acid and their salts or their submineral acid salts. The water-soluble film-forming inorganic compounds are superior in refractory, heat-resistant and heat-insulating properties, ...
Magnesium hydroxide can be formed by the reaction of the metal with water (Eqn (1.2)), which is the main reaction in the aqueous corrosion of magnesium. By comparing Eqns (1.1) and (1.2) it can be seen that both reactions have a similar thermodynamic tendency to take place. Therefore, ...
1), or chemically using chlorine gas and sodium hydroxide. (48)IO3−+6OH−+Cl2→IO65−+2Cl−+3H2O The product is actually dihydrogen orthoperiodate, Na3H2IO6, the parent acid being H5IO6. Orthoperiodic acid can be dehydrated to give metaperiodic acid (HIO4) by heating to 100°...
and is therefore magnetically shielded. The estimated structure does not involve the hydroxy group of4, indicating that this group does not serve as a base to promote the subsequent transmetalation with organoborons (Supplementary Fig.19). The observed formation of a zinc hydroxide oligomer as an...

Stearic acid may also be manufactured by the hydrogenation of cottonseed and other vegetable oils; by the hydrogenation and subsequent saponification of olein followed by recrystallization from alcohol; and from edible fats and oils by boiling with sodium hydroxide, separating any glycerin, and decomposi...
UsesSensitive reagent for iron, molybdenum, silver, tin. With ferric iron a blue color appears, and when an alkali hydroxide is added to a solution contg ferrous salts and thioglycolic acid, a yellow precipitate forms. Used in the manufacture of thioglycolates. The ammonium and sodium salts are...
Cement is calcium oxide, which becomes calcium hydroxide upon exposure to water. It usually contains lime, sand, and other metal oxides. The dry powder is very hygroscopic and will cause desiccation injury if not hydrated or washed away. Injury results from the action of the hydroxyl ion.50 ...
