What is sucrose analar?
Analar is deionised water, therefore sucrose analar is sucrose hydrated with deionised water.
Deionized water same as ethanol?
no, deionised water is still H20 just its been passed through an ion exchange resin to remove unwanted ions, ethanol is an alcohol with the formula CH3CH2OH.
Why is it necessary to rinse the conical flask with distilled water for titration?
It is necessary due to the conical flask may not be clean. deionised water is necessary as opposed to water due to the fact that alot of titrations if not all involve ions. if extra ions are added from the water the equivilance point could be off by a few tenths of a ml. Rinsing in general is necessary due to the fact that you never know what was held in the flask beforehand, and in nearly all cases it would upset your results. although, if you have no deionised water, it would upset your results less if you cleaned glasswear with normal water than if you used dirty glasswear. I recently won a competition that was part titrimetric, so I'm confident in my technique as thought by my lab technician. quick wash with tap water twice, then quick rinse with deionised twice. if anything impure remains, it will be so dilute that it shouldn't affect results.
What tool in chemistry should you use to measure acid?
A pH meter is an electronic device used for measuring the pH (acidity or alkalinity). In an emergency, acidified tap water can be used, but distilled or deionised.
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.
What is sucrose analar?
Analar is deionised water, therefore sucrose analar is sucrose hydrated with deionised water.
Is barium chloride soluble in deionised water?
Yes, barium chloride is soluble in water.
Can I Top up car battery with tap water?
no. use deionised or distilled water
Is deionised water a pure substance?
Yes it is because you are nutralising it from all impurifications
What is the difference between deionised and distilled water?
Distilled water: a water obtained by the distillation of water Deionized water: a water purified with ion-exchangers The two methods of water refining can lead to some minor differences between the final products.
Is the ultra pure water and the deionised water both are same?
Generally, yes; but is strongly recommended to read the manual of the water purifier or the specifications of the water in catalogs of chemical reagents, for comparison.
How do you prepare 1000 ppm of bromate from potassium bromate?
Dissolve 128 mg of potassium bromate in 100 ml of deionised water
What is a quick way to separate salt from water so you can drink the water?
Distillation or pass it through a deioniser, an ion exchange resin. I prefer distillation, deionised water always has a taste to it!

Why the deionised water still can be dangerous with the electrical appliances?
Even deionized water can be dangerous with electrical appliances because many such appliances contain nearby surfaces with a sufficiently high electrical potential difference between them to ionize water itself and thereby make the water electrically conducting.
