Material Based Design

Question 0

Ph value

Answer 0

A quantitive value that describes the material’s behavior as an acid or a base

Question 1

Chemical properties of materials

Answer 1

Ph value, corrosion resistance, toxicity, hygroscopy, reactivity, specific internal surface area, surface energy, surface tension

Question 2

Calculating Ph value from Hydrogen ion activity

Answer 2

Ph=log(1/[H+])

Where h+ refers to the hydrogen ion activity of a solution

Question 3

Hygroscopy

Answer 3

A material’s ability to attract water

Question 4

Dissicant

Answer 4

A high hygroscopy material, used as a drying agent

Question 5

Corrosion

Answer 5

The gradual chemical deconstruction of materials by the surrounding environment

Question 6

Corrosion resistance

Answer 6

The chemical ability of a metal to react more slowly with its surroundings

Question 7

Reducing corrosion

Answer 7

Alloy method

Plating method

Question 8

Galvinic Corrosion

Answer 8

A type of corrosion that occurs when two metals are in electrical contact with one another

Question 9

Factors in galvanic corrosion

Answer 9

Humidity, anode to cathode surface area ratio, metal types, temperature, salinity
