Yes, this is one of the many dirty little secrets of chemistry: There isn't any such thing as pure liquid water. Distilled water is a very dilute solution of hydroxide and hydronium ions, because (like many other solvents) water reacts with itself:
2 H2O() H3O+(aq) + OH-(aq)
At room temperature, about 1 in every 10 000 000 water molecules has dissociated by donating a hydrogen atom to another water. Distilled water under these conditions is actually 10-7MH3O+ and 10-7M OH-.
Hydroxide ion is the caustic component of lye, and hydronium ion makes acid solutions corrosive. However, the concentrations in water are extremely low and not at all dangerous. (For an opposing opinion about the toxicity of water, click here.)
Distilled water also reacts with atmospheric carbon dioxide according to
H2O() + CO2(g) H2CO3(aq)
H2CO3(aq) + H2O() H3O+(aq) + HCO3-(aq)
HCO3-(aq) + H2O() H3O+(aq) + CO32-(aq)
which brings the pH of distilled water in an open-air container down to about 5.8.
What else can I help you with?
Is salt water a colloid suspension or solution?
Salt water is a solution, not a colloid suspension. In a solution, the solute particles are dissolved on a molecular level and do not settle out. Colloid suspensions, on the other hand, have larger solute particles that do not dissolve and may eventually settle out.
Is water a colloid or suspension or a solution?
None of these. Water is a compound, which is a pure substance.
Is sand and water a solution colloid or suspension?
No, because the sand particles do not dissolve and in time will settle at the bottom making it a suspension.
Is water a colloid compound or a suspension?
salt water is a solution, since it dose not scatter light, and appears as one layer.
Is soil and water a solution suspension or a colloid?
Soil and water form a suspension when mixed together because the soil particles do not dissolve in water but remain dispersed throughout the liquid.
Is sand water is a solution or a colloid?
It is a suspension.
Is mouthwash a colloid?
Yes, mouthwash is a colloid. It is a liquid mixture containing suspended particles that do not settle out.
Is salt water a colloid suspension or solution?
Salt water is a solution, not a colloid suspension. In a solution, the solute particles are dissolved on a molecular level and do not settle out. Colloid suspensions, on the other hand, have larger solute particles that do not dissolve and may eventually settle out.
Is salt water a colloid emulsion solution or suspension?
Salt water is a solution, not a colloid, emulsion, or suspension. A solution is a homogeneous mixture where one substance dissolves in another at the molecular level. In the case of salt water, the salt (solute) is dissolved in the water (solvent) to form a uniform mixture.
Is water a colloid or suspension or a solution?
None of these. Water is a compound, which is a pure substance.
Is Soda a suspension or a solution or colloid?
Soda water is a solution of water and carbon dioxide gas.
Is salt water considered a suspension colloid or solution?
It's considered a solution but it can be separated by evaportaion.
Is sand and water a solution colloid or suspension?
No, because the sand particles do not dissolve and in time will settle at the bottom making it a suspension.
Is cordial in water a suspension or colloid?
Solution actually. Cordial is itself a solution, so adding water to it just changes concentration.
Is a cola soft drink a colloid solution or suspension?
A cola soft drink is a colloid solution, as it consists of water, sugar, carbon dioxide gas, flavorings, and other additives uniformly dispersed at the molecular level. It does not separate into distinct layers over time like a suspension would.
How can the word ''colloid'' be used in a sentence?
Wallpaper paste is a colloid. When you mix flour in water you form a colloid.
Is HCl a solution colloid or suspension?
HCl is a solution, not a colloid or suspension. A solution is a homogeneous mixture where one substance dissolves in another, as is the case with HCl dissolved in water. Colloids are mixtures with particles dispersed throughout, while suspensions have particles that can settle out over time.
