Acids, bases and salts topic 10

A chemical characteristic that helps determine how a substance dissolved in water will interact with and affect its environment.
ability of water to neutralize acid
Alkalinity is the capacity of water or wastewater to neutralize acids. This capacity is caused by the water’s content of carbonate, bicarbonate, hydroxide, and occasionally borate, silicate, and phosphate. Alkalinity is expressed in milligrams per liter of equivalent calcium carbonate. Alkalinity is not the same as pH because water does not have to be strongly basic (high pH) to have a high alkalinity. Alkalinity is a measure of how much acid must be added to a liquid to lower the pH to 4.5.
Arrhenius acid
A substance whose water solution contains the hydrogen ion as the only positive ion.
Arrhenius base
Produces hydroxide ions when dissolved in water. The presence of a hydroxide ion makes the base an electrolyte
Substances that conduct an electric current,
Hydrogen ion
a positively charged atom of hydrogen

Hydronium ion
hydrogen ion combines with a water molecule to form a hydronium ion, H3O(+)
A compound that changes color in the presence of an acid or a base
(chemistry) a substance that changes color to indicate the presence of some ion or substance
A reaction between an acid and a base
A reaction of an acid with a base, yielding a solution that is not as acidic or basic as the starting solutions were.
pH scale
measurement system used to indicate the concentration of hydrogen ions (H+) in solution; ranges from 0 to 14. O is most acidic + and 14 is most basic + or akaline.
A compound resulting from the formation of an ionic bond; also called an ionic compound.
A solution of known concentration is used to determine the concentration of another solution.
A laboratory procedure where a measured volume of one solution is added to a known volume of another solution until the reaction is complete.
