2)Sand does not dissolve in water.Filtration is a method for seperating insoluble solid from a liquid.Therefore,sand is a solid and water is a liquid so after the sands stays behind the filter paper,the sand will become a residue
3)Straining,filter paper,filter funnel and conical flask.
4)1stly wear saftely goggles.This is because the chemical might splash into your eye and could end up in an infection.2ndly,pay attention.This is because the chemical is going to react at anytime so be prepared and be attentive so you can see what is actually happening.Lastly,be careful.This is because we might need to be very careful to pour the mixture carefully into the filter paper and not pour on somewhere else.
5)To seperate particles and fluid.

The fluid that passes through is called the filtrate.Oversize solids in the fluid are retained, but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness). Filtration is also used to describe some biological processes, especially in water treatment and sewage treatment in which undesirable constituents are removed by absorption into a biological film grown on or in the filter medium as in slow sand filtration.]]> 2018-01-28 09:19:40 UTC https://padlet.com/neo_si_lie_charles/lj3pmdiaft1c/wish/225355662 What are the applications of the method? https://padlet.com/neo_si_lie_charles/lj3pmdiaft1c/wish/225359579 Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.  ]]> 2018-01-28 10:07:56 UTC https://padlet.com/neo_si_lie_charles/lj3pmdiaft1c/wish/225359579 What are the precautions,if any,to take note of the given method? https://padlet.com/neo_si_lie_charles/lj3pmdiaft1c/wish/225381338 none]]> 2018-01-28 14:08:25 UTC https://padlet.com/neo_si_lie_charles/lj3pmdiaft1c/wish/225381338 Using an example, of a suitable mixture describe how can we separate the mixture by filtration https://padlet.com/neo_si_lie_charles/lj3pmdiaft1c/wish/225468750 Step 1: Aim and Materials



Aim: To separate mud from water using filtration, but also purify the water afterwards.

Materials:
Dried Dirt (from the ground)
Bleach
x2 See Through Glasses
Water From The Tap
Spoon
x2 Filter paper
Funnel


Step 2: Method (Part1)



(1) Mix the dirt and water into one of the clear glasses. Mix until water is brown.

(2) Fold the filter paper in half, and then in half again. You should end up with a cone shape. Place inside the funnel.

(3) Put the other glass onto a flat surface and hold the funnel over it. Fill the cone filter paper(inside the funnel) halfway full of dirty water.

(4) Watch it drip through the filter paper and funnel. Your other glass should be filling up with clean water.


Step 3: Meathod (Part2)



(5) Once that has finished filtering, repeat steps 3 & 4, but using the other piece of filter paper. Wrince out the leftover dirty water and switch it with the glass full of dirty water, so that the glass of filtrated water is in your hand, and the other is underneath the funnel.

(6) Re-pour the filtrated water into the funnel and watch it drip into the clean glass.

(7) When done, add 2 drops of bleach (which contains chlorine) to your filtrated water. Stir for 1 minute.

Step 4: Analysis


When we poured the dirty water into the filter paper, the dirt didn't go through the filter, but the water did. This is because of the tiny holes in the filter paper.
