How made pure salt?
A good method of refining NaCl is repeated crystallization/recrystallization.
What are pure compounds?
A substance made from two or more elements in definite proportions. eg NaCl
Is salt a combination of 2 pure substances?
Pure salt, NaCL, is a chemical compound made from two elements. So yes it is a combination of two pure substances
Are HCl aq NaCl aq HCl g and NaCl s substances?
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
Which will have the lowest boiling point pure water 0.5 M NaCl aq 1.0 M NaCl aq or 2.0 M NaCl aq?
Pure Water
What is the name given to the substance that pure table salt is made from?
Table salt is NaCl, which is named sodium chloride.
Why NaCl turns colourless when melted?
NaCl pure is also colorless at room temperature.
Is salt mixture or pure substance?
pure substance...since it is NaCl...a compound..
Why is there difference in conductivity between 5 percent NaCl solution and pure NaCl?
Pure solide NaCl is not electrically conductive. The water solution of NaCl is an electrolyte and is conductive.
How many grams of nacl would you use to make 100ml of 0.9 percent nacl?
The answer is 0,9 g pure, dried NaCl.
Does Na-Cl have a pure covalent bond?
No NaCl has nearly pure ionic bond
Does salt have H2O in it?
Pure and dried salt (NaCl) has no salt.
