The solubility of sulphates in water decreases on moving down the group B e S O 4 and M g S O 4 are fairly soluble in water while B e S O 4 is completely insoluble. Reaction with chlorine All the s-block metals react directly with chlorine to produce chloride. It is combustible and supports the combustion of burning P, Mg or charcoal. solubility: sulphates of alkali metals are soluble in water. 2. Precipitates of s block, p block, d block elements; Precipitates categorized as anions and cations : This section is bit different. This is called inert pair effect. The general electronic external configuration for p block components is ns2np(1−6). Representative elements: Elements belonging to the s and p-blocks in the periodic table are called the representative elements or main group elements. P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. Non-metals are on the extreme right side of the periodic table, except for hydrogen, found in the upper left corner. Magnesium carbonate, for example, has a solubility of about 0.02 g per 100 g of water at room temperature. acid evolves ammonia which reacts with HNO, ACTION OF NITRIC ACID ON COPPER UNDER DIFFERENT CONDITIONS, Metals like Mg and Mn give hydrogen with dil. Solubility of sulphates: The solubility of sulphates of alkaline earth metals decreases as we move down the group from Be to Ba due to the reason that ionic size increases down the group. It is also called boron family. As an example chloride ion can be given. Mixture of Calcium Cyanamide and graphite under the name of nitrolim is used as fertilizer.
