A mixture of salt and water is always a solution.
A compound differs from a mixture in that a compound always has a
Not necessarily. A mixture can be anything that contains 2 or more substances, like sand and sugar or water and olive oil. In a solution one of the substances has been dissolved in the other, that is to say, one of them has been split up in parts too small to see with the naked eye. Styrofoam in gasoline is a solution. Sugar in water is also a solution and so is tea in water. The tea-leaves however have not dissolved and are not part of the solution.The easiest way to tell if something is a solution is to see if it is transparent (you could see though it, even if it's colored) or opaque.Yes, a solution is always a mixture, but a mixture is not always a solution.
The uses of litmus paper to find out the pH of solution. i.e., to check whether the solution is acidic, basic or neutral. Red litmus always turn to blue if the solution is basic. Blue litmus always turn to red if the solution acidic. They don't change their colour, if the solution is neutral. (7pH).

A mixture of salt and water is always a solution.
it is false as acid-base mixtures are neutral.
It is always a mixture of two substances: the solute and the solvent.
The liquid must be monophasic.

In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.
