Yes. The concentration of H+ and OH- ions is the same.
No. Pure water is neutral, it is neither acidic or basic. The concentration of H+ and OH- is exactly the same. There is an equilibrium present :-
H20 <-> H+aq +OH-
Pure - no.
The number of positive and negative ions will balance.
Yes. It contains very small amounts of H+ and OH- . The H+ are solvated, one common from is H3O+. The concentration of H+, [H+] is 10-7 mol/l. The concentration of OH- is the same.
no it doesnt
yes
an acid has more hydrogen ions than water.
There is no chart provided, thus cola cannot be compared to pure water. However, cola generally contains more H+ ions than pure water.
Acidic solutions have higher concentrations of hydrogen ions than pure water.
Yes, it does.
The concentration of hydrogen ions determines the pH. Since water is neutral with a pH of 7 or so, any substance with a lower concentration is acidic.

Acidic solutions have higher concentrations of hydrogen ions than pure water.
An acidic solution contains many more H+ ions than OH- ions, and a basic solution has more OH- than H+. A pure water solution, which is neutral, has exactly equal number of each.
These are acidic solutions.
Yes, it does.
acids
pure waterDiscussionDissolving something in water which does not evaporate easily will make the mixed solution less likely to evaporate than pure water. The more stuff you add to it, the less likely it will evaporate.Adding salt to water makes ions in solution and these ions reduce the vapor pressure of the solution compared to pure water. The lower the vapor pressure of a liquid or solution, the slower it will evaporate. This effect is also related to boiling point elevation and freezing point depression.
Pure water is neutral - pH 7 If a solution has a high concentration of H+ ions it is acidic and will have a pH between 0 and 6.9 depending on the strength of the acid.
Milk of magnesia is a solution of magnesium hydroxide (a white powder) in water. It is a base because when the powder is introduced into water, it partially dissociates (breaks up) into magnesium (Mg2+) and hydroxide (OH-) ions. Pure water contains an equal number of OH- ions and another ion called hydronium ions (H3O+). Because the milk of magnesia adds OH- ions to the water, there are now more OH- ions than H3O+ ions. This means you have a base. On the opposite end, if there are more H3O+ ions than OH- ions, which happens when you add vinegar or lemon juice to water, you have an acid. Hope that makes sense!
Cola has 10,000 x more h+ ions than pure water
Gases are less soluble in salt water than in pure water because the presence of salt ions in the water disrupts the hydrogen bonding between water molecules. This reduces the ability of gases to dissolve in the water, as the solubility of gases is primarily dependent on the strength of the intermolecular forces in the solvent. Additionally, the salt ions may also compete with the gas molecules for solvation, further decreasing gas solubility.
