Sulfurous acid, H2SO

Liquids that form conducting solutions are called ionizing solvents. A few other compounds (ammonia, NH3i sulfur dioxide, S02, sulfuric acid, H2SO<, etc.) are ionizing solvents but water is by far the most important. We will discuss water exclusively but the same ideas apply to the other solvents in which ions form. [Pg.169]

Self-Test 12.1B Acidified potassium permanganate solution reacts with sulfurous acid, H2SO. (aq), to form sulfuric acid and manganese(II) ions. Write the net ionic equation for the reaction. In acidic aqueous solution, H2S03 is present as electrically neutral molecules and sulfuric acid is present as HS04 ions. [Pg.607]

Alcohols can be dehydrated by a number of procedures. One method is to use a dehydrating agent such as phosphorus oxychloride (POCI3), and another method is acid-catalyzed dehydration using sulfuric acid (H2SO ) or phosphoric acid (HjPO ). An example of acid-catalyzed dehydration is in Figure 3-17, and the mechanism is shown in Figure 3-18. [Pg.41]

Notice that sulfuric acid (H2SO J is formed at two different points in this process, once during the oxidation of iron pyrites itself and once during the reaction between the iron(III) ion and iron pyrites. [Pg.124]

This sulfur dioxide gas dissolves in rainwater to form the weak acid, sulfurous acid (H2SOs). [Pg.195]

Regardless of whether a bond is covalent or ionic, the oxidation state can be calculated. The oxidation state of S in sulfuric acid (H2SO ) can be calculated through the oxidation rules above. Rule 3 makes each of the four oxygen atoms have a oxidation state of -2, and each hydrogen a +1. Overall it s known that the total molecule has no charge, so all the oxidation states must add up to 0. With these facts, you can easily determine the oxidation state (OS) of S ... [Pg.41]

As you have seen, NO2, SO2, and SO3 can both react with water in the atmosphere to produce acids NO2 produces nitric acid (HNO3) and nitrous acid (HNO2) SO3 and SO2 produce sulfuric acid (H2SO ) and sulfurous acid (H2SO3). When conditions are favorable, water droplets carrying these acids precipitate as rain or snow with a low pH. Ice core samples taken in Greenland and dating back to 1900 contain sulfate (SO ) and nitrate (NO ) ions. This indicates that at least from 1900 onward, acid rain has been commonplace. [Pg.226]

What mass of sulfuric acid, H2SO is required to react with 1.27 g of potassium hydroxide, KOH The products of this reaction are potassium sulfate and water. [Pg.832]
