Balance the following oxidation-reduction reactions: a. Mn2+ + BiO3- â†’ MnO4- + Bi3+ (in acid) b. NO3- + I2 â†’ NO2 + IO3- (in acid) c. ClO3- + S2- â†’ Cl- + S (in base) d. Mo(OH)3 + HO2- â†’ MoO4 2- (in base) If 0.542 mL of 0.0402 M KMnO4 is required to titrate 0.200 mL of NaI solution to the endpoint in acid, what is the concentration of iodide ion in the original solution? The products are Mn2+ and I2. Write the balanced redox equation in acidic solution.

00:01 Students let me explain you the question so in the first question they have asked the physical properties of iron so iron physical properties here they have asked so the physical properties of iron here it is so iron it is ductile malleable lustrous ductile malleable lustrous and also magnetic in nature these are the physical some of the physical properties of iron then coming to the chemical property of dynamite, chemical properties of dynamite.

00:35 So the dynamite, it is nothing but it is one of the explosive made up of nitroglyzerine.

00:43 So it is a explosive, it is made up of nitroglyzny.

00:48 This particular nitroglyzerine, so in the nitroglyzerine, carbon and hydrogen, so they react or they combined with the oxygen and the nitrogen, it is liberated out.

01:01 Nitrogen it is liberated out.

01:04 So then coming to the next one, what visual science indicates the visual signs.

01:11 That means it can be visible to the naked eye visual changes.

01:17 Visual science.

01:19 It indicates the chemical change.

01:23 So that is formation of gas bubbles.

01:27 Formation of gas bubbles.

01:29 So gas bubbles formed during the chemical reaction, chemical reaction.

01:37 So the formation of gas bubble during chemical reaction.

01:41 So that means chemical reaction occurred and the mixture becomes saturated with air.

01:48 And the mixture becomes saturated with air...
