Presentation Transcript

Slide 1

The properties of water Life relies on upon them!

Slide 2

Water is polar

Slide 3

Polar atoms Molecules are electrically unbiased. Segments of a particle can go about as if they have an electrical charge if the segments have diverse attractions for electrons.

Slide 4

Polar particles In water, the oxygen demonstrations negative and the hydrogens demonstration postive. Essentially, a water atom has a positive and a negative shaft, or end. As in magnets and particles, opposites are inclined toward one another.

Slide 5

Hydrogen bonds Polar particles with hydrogen iotas are unequivocally pulled in to the negative districts of other polar atoms.

Slide 6

Cohesion Hydrogen bonds shaping between water particles make them stick together. This is union. Attachment makes surface pressure.

Slide 7

Hydrogen bonds are capable

Slide 8

Adhesion Water atoms are additionally pulled in to different substances, particularly on the off chance that they convey an electrical charge.

Slide 9

High particular warmth The hydrogen bonds between water particles imply that a lot of vitality must be added or subtracted to bring about a state change: strong to fluid or fluid to gas. http://mutuslab.cs.uwindsor.ca/schurko/activitys/waterphases/status_water.htm

Slide 10

Ice is a separator Also, ice can go about as an encasing since it coasts: ice is less thick than water! Once more, hydrogen bonds are mindful.

Slide 11

High particular warmth This likewise implies water forestalls vast quick temperature changes in the earth.

Slide 12

Ice and water

Slide 13

Solutions Water is the all inclusive dissolvable . This implies it can break down numerous solutes , particularly polar particles. Water likewise causes ionic mixes to (separate into particles.)

Slide 14

Sodium chloride separates salt http://programs.northlandcollege.edu/science/Biology1111/movements/dissolve.html

Slide 15

Dissociation The "positive" hydrogens in water are pulled in to negative chloride particles. The "negative" oxygen in water is pulled in to positive sodium particles. A shell of water particles around the particles shields ionic bonds from transforming.

Slide 16

Water breaks up atoms Water particles will likewise encompass polar particles. Indeed, even genuinely substantial atoms with charged locales can be encompassed with water and broke down.

Slide 17

Water breaks down atoms

Slide 18

Suspensions Particles that are too extensive or are hydrophobic nonpolar particles won't disintegrate. On the off chance that enough vitality is included, the particles might be incidentally encompassed by water atoms, yet they in the long run isolate into a particular layer.

Slide 19

Liquid blends in science What are arrangements containing separated particles useful for? Disintegrated substances can be transported effortlessly, and moved crosswise over films. What is a natural suspension?

Slide 20

Acids and bases few water atoms (1 in 550 million or something like that) will separate suddenly. H 2 0  H + OH - Usually the centralizations of H + and OH - are adjusted and the arrangement is unbiased.

Slide 21

Acids If an answer contains an abundance of H + particles, the arrangement is said to be a corrosive. The convergence of H + particles is measured by the pH scale. A higher fixation implies a lower pH esteem.

Slide 22

The pH scale The pH (force of Hydrogen) scale keeps running from 0 to 14. Water, with equivalent groupings of H + and OH - particles, has a pH of 7.

Slide 23

Bases If there is an abundance of OH - particles, the arrangement is said to be a base, or an antacid. A fundamental arrangement has a low grouping of H + particles and a pH esteem over 7.

Slide 24

The pH scale http://www.johnkyrk.com/pH.html What sorts of materials are bases? What sorts are acids? What is the perfect pH of intravenous arrangements?

Slide 25

Acid rain Increasing fermentation of rain has extreme natural results.

Slide 26
