Question

Q. Why should distilled water be used when making chemical tests? PLEASE, use clear hand-writing*

*******PLEASE PLEASE PLEASE. someone answered this question before but in a bad hand-writing. although i asked for clear hand-writing!!!! PLEASE, IN CLEAR CLEAR CLEAR HAND-WRITING, CLEAR. MEANS EASY TO READ.

Answer 1

Because that is the only pure water.For experiments depending on what they measure impure water will change density,conducitivity,freezing point,boiling poinrt and corrosive and surface tension.

The imortant of a experiment is that it is documented as to procedure and items used and results should be reproduced accurately by a third party in a different place,if the water is different you get widely different results depending on properties of water taken.Distilled water minimises the potential of water in taking the test.
