How do you explain the relatively high conductivity of tap water compared to a low or zero conductivity for distilled water?
Tap water contains extra ions (ie not jusy H2O) which conduct. Deionised (as the name suggests) has no extra ions so it is just H2O and which does not conduct as it is not ionically bonded.
Are you able to adjust the Electrical Conductivity reading of water and how?
Yes, the electrical conductivity of water can be adjusted by adding or removing dissolved ions or salts. Increasing the concentration of dissolved salts will increase the conductivity, while decreasing the concentration will reduce it. This can be done through processes such as dilution or water treatment.
What is the zero correction and meniscus correction in hydrometer analysis?
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.
Why is the conductivity value of deionized water subtracted from the conductivity values of molecular compounds?
The conductivity value of deionized water is subtracted from the conductivity values of molecular compounds to remove the background contribution of water to the conductivity measurement. This subtraction allows for a more accurate assessment of the conductivity solely due to the molecular compound being tested.
What is a real world example of solution conductivity?
A PH meter measures conductivity to tell the amount of Hydrogen in a solution. A conductivity meter is used to measure the purity of water in ohms. A battery is a great example of solution conductivity at work.
Why is the conductivity of purified water not zero?
conductivity is not zero because water itself has ions i.e. H+ & OH- so conductivity cannot be zero. even if you use EDI still some conductivity will be left it will be almost negligible but still conductivity will be there.
Is the temperature reading of zero on the Celsius equal to absolute zero?
No. Absolute zero is -273 degrees celsius. A reading of zero celsius is the freezing point of water.

How do i confirm that this water is demineralized water?
The commonest test is to check the electrical conductivity between two electrodes. Pure water has very poor conductivity, but the conductivity improves as more ions are dissolved in it. Sea water has a conductivity of around 5 S/m (Siemens per metre) Drinking water has a conductivity of 0.005 - 0.05 S/m . Ultra-pure water has a much lower conductivity of 5.5 x 10-6 S/m - a million times smaller than that of sea water.
What do Zero Reading mean?
A Zero Reading can mean a multitude of things depending on the context. In a velocity reading a Zero Reading would indicate no overall movement. Example, if a runner ran from point A to point B continuously this would be a Zero velocity Reading.
Why would the bath water have electrical conductivity?
Pure water has extremely low conductivity but any dissolved salts in the water increase its conductivity. Sea water with 3% salt has a high conductivity of 5 S/m.
What is the relationship between the purity of water and its conductivity?
The purity of water is inversely related to its conductivity. Higher purity water has lower conductivity because impurities in water, such as minerals and ions, increase conductivity by allowing the flow of electric current.
What is the unit of conductivity of dm water?
Unit of dm water conductivity is microsiemens/cm
What is the zero correction and meniscus correction in hydrometer analysis?
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.
How can the resistivity of water be measured?
The resistivity of water can be measured by using a device called a conductivity meter, which measures the electrical conductivity of the water. The higher the electrical conductivity, the lower the resistivity of the water.
Which conductivity of water is better Either low conductivity of water is better or high conductivity of water is better?
Low conductivity of water is generally better as it indicates fewer dissolved ions or impurities in the water. High conductivity can be a sign of contamination or high mineral content, which may not be suitable for certain applications like electronics or drinking water.
