What water freezes faster cold water or fluoride water?
Cold water freezes faster than fluoride water. This is known as the Mpemba effect, where the freezing point of water is lowered when certain substances like fluoride are added, making it take longer to freeze than regular cold water.
Does water have fluoride?
Pure water does not contain fluoride, but much drinking water does contain fluoride that is deliberately added to reduce tooth decay of children who drink the water. Some drinking water supplies also contain fluoride naturally.
Is pure water a mixture a compound or a element?
No. It is a compound made of the elements oxygen and hydrogen: H2O.
Is a potassium dichromate a pure substance or a mixture in dissolved water?
Potassium dichromate is a pure substance in solid form. When dissolved in water, it forms a solution, which is a homogeneous mixture of potassium dichromate and water molecules.
Is Pure water an element or a compound?
Pure water is a compound as it consists of two elements, hydrogen and oxygen. Its chemical formula is H2O.
Name two compounds which are covalent when pure but ionise to give ions when dissolved in water?
Hydrogen chloride and hydrogen fluoride are two examples of compounds that are covalent when pure but ionize to give ions when dissolved in water. When dissolved in water, hydrogen chloride forms H+ and Cl- ions, and hydrogen fluoride forms H+ and F- ions.
Is sodium fluroide an elctrolyte?
Yes: If sodium fluoride is dissolved in water, the solution will conduct electricity, as will pure sodium fluoride if it is hot enough to melt.
What is added to hydrogen chloride gas to make hydrochloric acid?
Water. Hydrochloric acid is just hydrogen chloride gas dissolved in pure water.
is tap water in a glass pure substances or mixture?
Tap water is not a pure substance. Water has particles in it. Some tap water also contains fluoride. Distilled water has all of the particles taken out of it and is considered pure water.
Is pure water a solution?
Absolutely pure water is not even that. Water dissociates itself into dissolved hydroxide and hydrogen ions, the latter forming hydronium. It is thus a solution of both of these ions.

What is the solubility of Xenon Tetrafloride?
XeF4 reacts with water - or even moisture in the air - to release pure xenon, hydrogen fluoride and molecular oxygen.
What water freezes faster cold water or fluoride water?
Cold water freezes faster than fluoride water. This is known as the Mpemba effect, where the freezing point of water is lowered when certain substances like fluoride are added, making it take longer to freeze than regular cold water.
Is your tap water pure water?
No, it has chlorine in it, and sometimes fluoride, as well.
Is there any fluoride or chloramine in distilled water?
Distilled water is pure.
Is water pure or a compound?
Pure water is a compound of hydrogen and oxygen.
Is hydrochloric acid a homo or hetero mixture or pure substance element or compound?
Hydrogen is a pure substance because it is an element
