Why is the pH meter placed in distilled water before testing each solution?
Not the pH-meter, but the electrode.
If distilled water has a hydronium ion concentration of 1x10-7M what is the pH of a distilled water?
Distilled water has a pH of 7. It's neutral.
What is distilled water on a pH scale?
Distilled water, if it is truly distilled to purity, has a pH of 7. This means that the concentration of hydrogen ions dissociated from the water is 1x10-7 mol dm-3. Often, distilled water is impure, and is slightly more acidic (it has a slightly lower pH than seven).
PH of triple distilled water?
7.00
Is the solution Distilled Water acidic alkaline or neutral?
Distilled water is theoretically neutralDistilled water is water that has many of its impurities removed through distillation.Distillation involves boiling the water and then condensing the steam into a clean container.Hypothetically, distilled water should always be at a neutral pH 7. Immediately upon being exposed to air, however, distilled water's pH decreases and becomes more acidic. Neutralizing distilled water is possible, but its neutral pH does not last.

why is it important to calibrate a pH meter before you used it?
checking ph
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.
How do you calibrate a pH meter?
it is placed in a buffer solution of 7.0 then it is placed in a buffer having pH 4.0
What is pH for distilled water?
the pH of distilled water is 7.0 and is the same as pure water The solution is acidic.
If distilled water has a hydronium ion concentration of 1x10-7M what is the pH of a distilled water?
Distilled water has a pH of 7. It's neutral.
What precaution should be taken carrying experiment using pH meter?
wash the pH probe with distilled water and then dry it clean with tissue paper before and after testing the pH.
Give two solutions that can be used to calibrate the pH meter?
Standard buffer solution
