B.The reaction will proceed to the left.C.More I2 will form.E.HI will be consumed.
2H+ + SO42- + Ca2+ + 2I- CaSO4 + 2H+ + 2I-
2ki+ h2so4 ----> k2so4 + 2hi
2HI + Ca(OH)2 --> CaI2 + 2H2O
2H+ + SO42- + Ca2+ + 21 > CaSO4 + 2H+ + 21-
B.The reaction will proceed to the left.C.More I2 will form.E.HI will be consumed.
2H+ + SO42- + Ca2+ + 2I- CaSO4 + 2H+ + 2I-
H2(g) + I2(g) 2HI(g)18.6
2ki+ h2so4 ----> k2so4 + 2hi
1Ca(OH)2 + 2HI ---> 2H2O + 1CaI2
2HI + Ca(OH)2 --> CaI2 + 2H2O
H2 + I2 -> 2HI If you want a word for reactions that don't involve elemental oxygen, "anaerobic."
2H+ + SO42- + Ca2+ + 21 > CaSO4 + 2H+ + 21-
There will be no reaction between Hydrogen Iodide and sulphuric acid. If the acid are is dilute a soution of both will be formed, if the acid is concentrated these compounds are immiscible. hydrogen iodide and sulphuric acid are actually a product of a reaction (known as the Bunsen reaction) 2H2O + SO2 + I2 → H2SO4 + 2HI
"HI" is a latin word, its real meaning is horiontal roll, now u can easly understand the meaning of 2hi, 4hi, 6hi & 20 hi , for example 2hi mean two horizontal roll which is used for rolling the iron.
SrCO3+2HI=SrI2 solution + CO2 => evaporation to temperature of solution 130oC => slow vacuum drying in quartz ampule to 150oC
The balanced equation is as follows: 2HI + Cl2 --> 2HCl + I2
