For these three oxides, state whether each one is acidic, basic or amphoteric. Explain how cation oxidation state can be used to help predict acid/base behavior. CrO CrO3 Cr2O3 (a) Briefly explain what amphoterism means; (b) Choose an amphoteric molecular compound and indicate its chemical reaction with an acid and with a base.
For each metal lower oxidation state are basic and higher oxidation states are acidic. Elucidate with suitable example. CF3COOH is strong acid and (CH3)3N has no basic property - is there any common reason?
C. Explain about solubility of an amino acid when subjected to an
acidic media and basic media. Indicate the compound which would be
at the isoelectric point. (Draw a diagram to help
explain)
c. Explain about the solubility of and amino acid when subjected to an acidic media and basic media. Indicate the compound which would be at the isoelectric point. (Draw a diagram to help explain). (3 marks) Amino acids are the building blocks of proteins, acidic amino acids...
9. State whether the following oxides are acidic, basic, neutral, or amphoteric: CO2, P2O5, SO3, MgO, K2O, Al2O3, CO. 10. Preferably without consulting reference material, write out the halogens as they appear in the periodic table, and indicate the trends in (a) physical state (s, l, or g) at room temperature and pressure, (b) electronegativity, (c) hardness of the halide ion, (d) colour.
Explain why the +3 oxidation state becomes increasingly less stable with respect to the +2 oxidation state on moving from left to right across the first row of the d-block elements.
The oxidation state of a transition metal can be determined by looking at the ligands bonded to the metal. Every bond to a transitie by +1. For example in CoBry, there are two bromines bonded to the cobalt, and the cobalt will have a +2 oxidation state (Co?"). W to the metal, they do not change the oxidation state of the metal. For example the palladium in Pd(PP), has an oxidation state Determine the oxidation state of the metal in...
Oxidation-Reduction Equation Balancing in Acidic Solution and Basic
Solution.
Balance the "breathalyze" test reaction in acidic solution, as in example 18.2 on tro C_2H_5OH + Cr_2O_7^2- rightarrow CH_3CO_@H + Cr^3+ Balance in basic solution as in example 18.3 on p Fe(OH)_3 + SnO_2^2+ rightarrow Fe + SnO_3^2-
In many species, a transition metal has an unusually high or low oxidation state. Write a balanced equation (including states) for the following and find the oxidation state (e.g., +2) of the transition metal in the product: Iron(III) ion reacts with hypochlorite ion in basic solution to form ferrate ion (FeO,,cr, and water Include the states of all reactants and products in your equation. 3- 2Fe (aq) +100H (ag) 3C10 (ag)-3C! (aq) 2Fco. (aq) +31 (aq) +5H,01) Oxidation state of...
