write the chemical formula for the following hydrates. use the proper symbols, case, and formatting. a. iridium(iii) bromide tetrahydrate b. tin(iv) chloride pentahydratec. zinc nitrate hexahydrate d. sodium carbonate monohydrate
we are asked to write the chemical formula of hydrates and to use proper symbols, case, and formatting.remember that an ionic hydrate is formed when an ionic compound is bonded to one or more molecules of water. naming ionic hydrates has the same set of rules in naming the ionic compound portion. the water molecule portion is named with a numerical prefix together with the word hydrate.[readmore]step 1: discuss the rules in naming ionic hydrates.step 2: from the naming rules, extract the chemical symbols and the formula for each of the compounds.step 1: discuss the rules in naming ionic hydrates.rules in naming the ionic compound portion:1.a. the metal is named and normally written first.-if the metal is a transition metal we must use a roman numeral to describe its positive charge.1.b. the nonmetal keeps the first part of its name but has its ending changed to -ide.1.c. name the polyatomic as you would normally.rules in naming the h2o portion:1.d. the h2o portion will be called hydrate.1.e. to describe the number of h2o molecules, use the numerical prefixes.note: a dot (•) is written in between the ionic compound and the hydrate.step 2: from the naming rules, extract the chemical symbols and the formula for each of the compounds.a. iridium(iii) bromide tetrahydrate rule 1.a.iridium→transition element → symbol : iriii → describes the transition element's positive charge → symbol: 3+rule 1.b.bromide → nonmetal bromine → bromide ion has a charge of -1 → symbol: brwe write the metal and nonmetal beside each other. recall that the charges will be exchanged, becoming subscripts in the chemical formula.we don't need to write 1 as a subscript, it is understood to be 1 without it.rule 1.d.hydrate → h2orule 1.e.tetra → four → 4therefore the chemical formula is irbr3•4h2o.b. tin(iv) chloride pentahydraterule 1.a.tin(iv)→ sn4+rule 1.b.chloride → cl-we write the metal and nonmetal beside each other. recall that the charges will be exchanged, becoming subscripts in the chemical formula.again, we don't need to write 1 as a subscript.rules 1.d and 1.e.pentahydrate → 5 h2o the chemical formula is sncl4•5h2o.therefore the chemical formula is sncl4•5h2o.c. zinc nitrate hexahydrate rule 1.a.zinc→ zn1+rule 1.c. nitrate → no31-we write the metal and nonmetal beside each other. recall that the charges will be exchanged, becoming subscripts in the chemical formula.note that +1 and -1 charges just cancel out, we just put the atoms together.rules 1.d and 1.e.hexahydrate → 6 h2othe chemical formula is znno3•6h2o.therefore the chemical formula is znno3•6h2o.d. sodium carbonate monohydraterule 1.a.sodium→ na1+rule 1.c. carbonate → co32-we write the metal and nonmetal beside each other. recall that the charges will be exchanged, becoming subscripts in the chemical formula.again, we don't need to write 1 as a subscript.rules 1.d and 1.e.monohydrate → 1 h2o → h2o     (we don't need to write 1 as a coefficient.)the chemical formula is na2co3•h2o.therefore the chemical formula is na2co3•h2o.
i. given:valency of carbon is 4valency of chlorine is 1by applying criss-cross method:formula: ccl4thus, the formula for carbon tetrachloride is ccl4.ii. given:valency of element x is 1valency of oxygen is 2by applying criss-cross method:formula: x2o Tin(II) chloride can dissolve in less than its own mass of water without apparent decomposition, but as the solution is diluted, hydrolysis occurs to form an insoluble basic salt:

 

Therefore, if clear solutions of tin(II) chloride are to be used, it must be dissolved in hydrochloric acid (typically of the same or greater molarity as the stannous chloride) to maintain the equilibrium towards the left-hand side (using Le Chatelier's principle).
