To prepare a dilute solution.
The pH become lower.
Adding nothing to the water should not affect the rate at which the water freezes. Adding substances, though, can noticeably depress the freezing point so that it will take longer to freeze than pure water under the same conditions. Salt is commonly used for this purpose. Adding nothing to water isn't expected to do anything to the rate at which it freezes.
Adding a base
Adding base will increase pH-level
Adding a salt to water we obtain a solution (a homogeneous mixture) not a new chemical compound.
the two together get and trap dirt and bacteria.
The pH become lower.
Adding a "Base" compound will do it.
The products of a neutralization reaction are water and a salt.
The base word of "unintentional" is "intentional." By adding the prefix "un-" to "intentional," the meaning changes to signify something not done on purpose.
The purpose of water washing the organic layer is for aqueous extraction to remove impurities and or reagents that are water soluble. For instance, in reactions that utilize a small tertiary amine base or inorganic base.
One would normally add water or some other solvent to dilute a base

Adding a base
The acidity can be lowered by adding a base.
To decrease the pH of the pool, hopefully keeping it at whatever alkalinity/acidity you desire.
Yes. Ph is a measurement of the concentration of the hydronium ion [H+]. If you add more water you change the concentration.
