The reaction is given below. “REDOX” • Is a chemical reaction in which electrons are transferred ... • Example: When metal is placed into hydrochloric acid solution, gas bubbles form as the zinc slowly disappears. Reaction Type. Zn (s) in 3M HCl (aq). 0000005636 00000 n 0000002428 00000 n 0000004665 00000 n Equation: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) ionic equation: Zn(s) + 2H+ (aq) + 2Cl- (aq) → Zn 2+(aq) + 2Cl-(aq) + H2(g) Zn has gone from Zn → Zn 2+ it has lost two electrons - it has been oxidised. What mass of silver nitrate must be placed into a 500 mL volumetric flask, dissolved, and diluted to the mark When zinc metal is submerged into a quantity of aqueous HCl, the following reaction occurs (Figure 5.4 "Zinc Metal plus Hydrochloric Acid"): Zn (s) + 2HCl (aq) → H2(g) + ZnCl2(aq) This is one example of … trailer << /Size 51 /Info 7 0 R /Root 10 0 R /Prev 102508 /ID[] >> startxref 0 %%EOF 10 0 obj << /Type /Catalog /Pages 6 0 R /Metadata 8 0 R /PageLabels 5 0 R >> endobj 49 0 obj << /S 48 /L 149 /Filter /FlateDecode /Length 50 0 R >> stream One of the reactants is an element and one of the products is an element. http://www.education.com/study-help/article/oxidat...

If you immerse a piece of metallic zinc in a solution of copper sulfate, the surface of the zinc quickly becomes covered with a coating of finely divided copper. Because of this, Zn has been oxidized to Zn 2+, while Cu 2+ has been … Zn (s) + 2H+ (aq) = Zn2+ (aq) + H2 (g): Zinc is oxidized, loses electrons. This means the reaction is spontaneous and Zn … Whichever way I write it out, I cannot reach the correct answer. N| δl붥BN:���. A.Yes; Al is reduced and H+(aq) is oxidized.B.Yes; Al is oxidized and H+(aq) is reduced.C.No; Al is reduced and Cl-(aq) is oxidizedD.No; Al is oxidized and H2O(l) is produced.So I understand that since the Zn … Oxidation Is Loss, Reduction Is Gain (of electrons). 0000074193 00000 n 0000006719 00000 n 0000001521 00000 n Does the water used during shower coming from the house's water tank contain chlorine?

Hydrogen is reduced, gains electrons. This means that Zn has lost two electrons to Cu 2+. This reaction would be classified as a redox single displacement reaction. Still have questions? with water? This reaction would be classified as a redox decomposition reaction. In the process, hydrogen gas is produced. Redox is a leading distributor of chemicals and ingredients, active in more than 1,000 specialty and commercial products.
