acid and bases

Neutralization

A double replacement reaction that produces salt and water; also known as acid-base reactionthat occurs when an acid reacts with a base to produce a neutral solution.

pH Indicator

Changes color when there is a change in the concentration of hydrogen ions in the solution

Arrhenius Base

When in water it dissociates into hydroxide ions plus cations, increasing the pH of the solution

Buffer

A combination of weak acid and its conjugate base that resists changes in the concentration of hydrogen ions

Brønsted Lowry Base

Accepts a proton from another chemical

Salt

An ionic compound that forms by neutralization

Weak Acid

Molecular compound that, when stirred into water, remains mostly intact but a tiny fraction releases a proton of hydrogen

Conjugate

Upon accepting one proton of hydrogen it becomes the _____ acid; now it has one more proton of hydrogen in its formula

pH

Inversely related to the concentration of protons of hydrogen in the solution: its value increases when proton concentration decreases

Acidic

A solution with a pH less than 7, which has a higher concentration of hydrogen ions compared to pure water.
