The pH of a solution can be less than zero. Remember that pH is defined as the negative logarithm of the hydronium ion concentration, pH = -log[H3O+]. For pH to be negative, the log of the hydronium ion concentration needs to be positive. The log of a number is only positive if that number is greater than one. For example, the value of log(2) is about 0.30. This means that the pH of a strong acid that has a concentration of greater than 1 molar will be negative.
An acid exists in aqueous solution when the concentration of H+ ions is higher than that of OH- ions, resulting in a pH lower than 7. A base exists in aqueous solution when the concentration of OH- ions is higher than that of H+ ions, resulting in a pH higher than 7.
Iodine is not reactive with potassium chloride in an aqueous solution because iodine is less reactive than chlorine. Chlorine is more likely to react with potassium to form potassium chloride, leaving the iodine unreacted.
An aqueous solution that contains more hydroxide ions than hydrogen ions is considered a basic solution with a pH greater than 7. This solution is known as an alkaline solution and has a higher concentration of hydroxide ions, making it a stronger base.
The term applied to an aqueous solution with a hydrogen ion concentration (H+) lower than the hydroxide ion concentration (OH-) is basic or alkaline. This indicates that there are more OH- ions present, making the solution basic on the pH scale.
An aqueous solution of a base is called an alkali solution. Alkalis are compounds that release hydroxide (OH-) ions in water, leading to an increase in the concentration of hydroxide ions in the solution. This results in a solution with a pH greater than 7.

Any aqueous solution will have a pH lower than 7.00 in order to be considered acidic.

When aqueous bromide and aqueous silver nitrate are mixed, a white precipitate of silver bromide is formed due to a double displacement reaction. The balanced chemical equation for this reaction is: AgNO3(aq) + KBr(aq) → AgBr(s) + KNO3(aq)
No, Mn is a transition metal and is typically found in solid form rather than in aqueous solution.
Yes, it is correct.
For a solution to be unsaturated, it means that more solute can be dissolved in the solvent; the saturation point has not been reached. This unsaturated aqueous sodium chloride is just a solution of common salt that can still have more NaCl dissolved in it.
Colligative properties, such as boiling point elevation, depend on the molality of the solution and the number of "entities" (ions, in this case) per formula unit. For the solutions specified, these are identical, so the answer is no.
In solution, sugar molecules can more easily reach the "sweet" receptors in the tongue.
