5. Selenic acid (H2SEO4) is a powerful oxidizing acid that dissolves not only silver (asdoes the related acid H2SO4) but gold, through the following reaction:2 Au (s) + 6 H2SEO4 (aq) → Au2(SeO4)3 (aq) + 3 H2SEO3 (aq) + 3 H2O (I)Determine the oxidation numbers of the atoms in this equation. Which species isoxidized and which is reduced? Hint: the selenate (SeO42-) and selenite (SeO3²-)polyatomic ions present in the above reaction are analogous to the sulfate andsulfite ions.

Oxidising agent: the compound or species oxidise to other component and itself get reduction.…

Sodium hydrogen carbonate NaHCO3, also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid HCl, which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl(aq)+NaHCO3(aq)→NaCl(aq)+H2O(l)+CO2(g) The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 50.mL of a 0.027M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl? Be sure your answer has the correct number of significant digits.
Soft drinks such as Coca Cola and Pepsi are acidic due to the presence of dissolved carbon dioxide that forms carbonic acid. Assume none of the carbonic acid exists as dissolved carbon dioxide. The dissociation of carbonic acid is: H2CO3(aq) =HCO;(aq) + H*(aq) For the problem, assume that the bicarbonate ion, HCO3', does not dissociate again to form the carbonate ion. In order to determine the acidity of a 355 mL can of soda, 0.500 M NaOH is titrated in, taking 25.78 mL to fully neutralize the carbonic acid. This leads to the result that there was 0.0129 mol H2CO3 in the can, with an initial pH of 2.32. (a) After the titration, what major species are present in the solution, and which will dominate the pH? (b) Which of the following acid-base equilibrium reactions determines the pH after the titration? I. H;CO3(aq) =HCO3 (aq) + H*(aq) Ka = 2.51×104 II.
