The purpose is to clean the probe and to avoid contamination of samples.

Why is the pH meter placed in distilled water before testing each solution?
Not the pH-meter, but the electrode.
How does the hydrogen bonding between water molecules affect the properties of water?
It enables water molecules to stick to each other and to many other things.
What type of bond is a strong chemical bond between the atoms of each water molecule?
covalent
Which type of symbiosis is the association between Anabaena and the water fern?
they have mutualism relationship, which both get benefit from each other
When a glass full of ice melts why is the volume of water less?
It's because water is a freak of nature in this sense hah. When water is a liquid there is less room between each molecule of water, because it isn't a uniform structure all the way through it. When water freezes it has a specific structure all the water through it which has more space between each molecule. Since it has more empty space in the ice it is less dense than water in it's liquid form.

What would happen to the mass of each bag in this experiment if all the bags were placed in 0.4 M sucrose instead of distilled water?
What experiment?
How do you add water to a Yamaha 125 Atv battery?
If it is a sealed battery you cannot. If it has fill caps, then remove the caps and fill each cell to the full mark with distilled water.
How to Calibrate and Use a pH Meter?
A pH meter is normally something that an environmentalist or chemist would use, but some gardeners also make use of it. This meter is used to measure the acidity and alkalinity of a specific liquid. pH is the measure of how many hydrogen ions are present in a solution. Although the meter is very easy to use, it must be cleaned after each time it is used to get a clear reading.Before you can begin to calibrate your pH meter, you must make sure that the probe you use was kept in a storage solution or a solution with pH 4. If you do not do this, you need to let the probe sit for at least twenty four hours in distilled water. The meter must also be set on pH mode or this will be pointless. When it is set, you should rinse it off with distilled water. To help calibrate it, it will be placed into a solution of pH 7. But before you put it in, make sure that you shake off any distilled water or solution that was left on it.The probe should be left in the pH 7 solution for at least thirty seconds. This will let the meter stabilize completely so you can change the meter. You should now have the meter at a reading of pH 7. Now, you should take the probe out and rinse it off again. Then, put it into a solution of pH 4. Again, the meter will need a minute to stabilize. Then, you can change the meter to a pH 4 reading. At this point, the meter should be fully calibrated.You must rinse off the probe again with distilled water and shake off any remaining liquid to get the correct reading. Now, you can put the probe into your liquid sample for a clear reading. You need to let the pH reading settle for about a minute to be more precise. You can now get the pH reading from your sample. When you are completely finished using your probe, you should keep it in a storage solution or a solution of pH 4.
What to do if your car battery is dry?
Add distilled water to the battery cells. Get the water just so each cell in underwater. And then find out why it is dry. Could be the voltage regulator is defective and the battery is being overcharged.
What are some well known brands of water distillers?
Distilled water comes from condensing steam. There are four major brands of water distillers worldwide, which are Polar Bear, Durastill, Pure Water and West Bend, each of which has over 20 years in the business.
When do you put water in your car?
Not recommended to use straight water. You should add a mixture or 50% each of water and Anti-freeze when the coolant level is below the add mark on the reservoir. Use only distilled water to prevent minerals from corroding the radiator.
How do you put water in mini cooper battery?
Batteries that are not maint. free have caps that pop off & you add distilled water up to the bottom of each cell. The water will take on a concave apearance when it hits-this is when you stop & move on to the next cell.
Why the burette and the pipette are each rinsed with distilled water and finally rinsed with some of the solution that will be measured or transferred?
These are conditions necessary to avoid contamination or any other modification of the reagents.

Does salt soulution conduct eletricity?
Most definitely! Pure water has no free electrons and is, in theory, a perfect insulator. Any impurity added to the water allows it to conduct electricity. You can prove this by taking a beaker (very clean and rinsed with distilled water) and fill it with distilled water. Connect a cord to a light socket and install a good lamp. Break in to one of the conductors and connect each side of the break to a strip of copper and insert the copper strips into the beaker of distilled water. Make sure the strips don't touch each other. Plug in the cord. The lamp will not light If copper is not available simply strip about an inch of insulation off the cord on either side of the break. Have someone plug in the cord. Holding the cord by the insulation on each side of the break, insert each bare section into the water. The lamp will not light. Now add salt to the beaker and repeat. The lamp will light. bright.
