Tap Water has higher conductivity compared to deionized water since it has more mineral/ salts. Deionized water has less/ no minerals to conduct electrical current. One can experiment this in a your Water Fuel Cell using deionized water, tap water and water with salts like (KOH or NaOH) or sea water.

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.
Why conductivity is increase of stored dm water?
The increase in conductivity of stored deionized water may be due to the absorption of carbon dioxide and other contaminants from the environment. These impurities can dissolve in the water, increasing the concentration of ions and hence the conductivity. It's important to store deionized water in clean, non-reactive containers to minimize contamination.
How is deionized water made and what is the process involved in its production?
Deionized water is made by removing ions and impurities from regular water through a process called deionization. This involves passing the water through special filters or resins that attract and trap the ions, leaving behind pure water with a very low conductivity.
What is conductivity and pH value of dm water?
The conductivity of deionized water (DI water) is typically very low, ranging from 0.5 to 3 µS/cm. The pH value of DI water is generally around 7, making it neutral. Conductivity measures the ability of water to conduct electricity, while pH measures the acidity or alkalinity of a solution.
Is distilled water the same as deionized water?
No, distilled water and deionized water are not the same. Distilled water is created by boiling water and collecting the steam, while deionized water is purified by removing ions and minerals.
How to test the purity of deionized water?
To test the purity of deionized water, you can use a conductivity meter to measure the electrical conductivity. The lower the conductivity, the purer the water. Additionally, you can use a Total Organic Carbon (TOC) analyzer to check for organic impurities. Conducting these tests will help determine the purity of deionized water.

What is the resistivity of deionized water and how does it affect the conductivity of the solution?
The resistivity of deionized water is high due to the absence of ions. This means it has low conductivity because there are fewer charged particles to carry electrical current.

Is deionized water an element?
The deionized water is not an element, but it is a very pure water, without ions in solution.
Is distilled water the same as deionized water?
No, distilled water and deionized water are not the same. Distilled water is created by boiling water and collecting the steam, while deionized water is purified by removing ions and minerals.
What is the resistivity of deionized water?
The resistivity of deionized water is typically around 18.2 megaohm-cm.
Is deionized water a mixture?
No, deionized water is not a mixture. It is a type of water that has had its ions (charged particles) removed through a process called deionization, resulting in a more pure form of water with a neutral pH.
What is the conductivity value of distilled water compared to deionized water?
Distilled water typically has a conductivity value ranging from 0.5 to 3 μS/cm, while deionized water has a lower conductivity value, usually less than 1 μS/cm. This difference is because deionized water has fewer ions present due to the removal of ions during the deionization process.
What is the function of deionized water in determination of ash content?
Ash content is determined by calcination and deionized water is not necessary.
