In this reaction redox products are also formed. List all of the redox products produced from the reaction between solid potassium bromide and concentrated sulfuric acid and give observations for any products.
Explain why the reaction between solid potassium iodide and concentrated sulfuric acid produces hydrogen sulfide whereas the reaction between solid potassium bromide, and concentrated sulfuric acid does not.
Hydrogen halides, H-X, are formed from the reaction of hydrogen and a halogen, X2. In solution hydrogen fluoride is classed as a weak acid, whereas HCl is classed as a strong acid. Explain this difference.
Potassium reacts with water to form hydrogen gas. Using sections 1 and 2 of the data booklet, determine the volume, in cm3, of hydrogen gas that could theoretically be produced at 273 K and 1.01105 Pa when 0.0587 g of potassium reacts with excess water.
