1. from the following standard electrochemical potential (and your knowledge of biomedically important metals), answer the questions below. reaction δeº(v) ti -> ti+3 2.00 al -> al+3 1.70 cr -> cr+2 0.56 h2-> 2h+ 0.00 au -> au+ -1.68 a. which metal would be the most anodic? b. which metal would corrode the most? c. which metal would be the most reactive? d. why can ti and au be used for making implants, but not al?

The following answer are based only on emf values

a).Most anodic element ,Titanium - Ti

b).Metal That will corrode easily is : Titanium - Ti

c). Most reactive metal is Titanium-Ti

d).Al can't be used for making implants because it undergo corrosion easily and do not form strong passive oxide layer.

Ti forms very strong passive layer which prevents further corrosion.

Au is least reactive and does not corrode.

Note : You have to give answer according to E values

Explanation:

Here the oxidation potential data is given (since elements are getting oxidised)

 : Standard Reduction Potential : It is tendency of the element to gain electron and get reduced.

Oxidation Potential is opposite to reduction potential

Standard Oxidation Potential :It is tendency of the element to loose electron and get oxidised.

It is measured in Volts/V

The main application values is in electrochemical cell to predict the products of the reaction. or  predict whether the reaction is spontaneous or not.

Since has maximum value of  = 2.00V , so it get oxidised as compared to other elements.

From the , E values Ti show maximum tendency of oxidation hence it also get corroded easily.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
