Acids & Bases

pH – concentration of H+

- indicates how acidic or basic a solution is

Acids & Bases

pH scale:

0-----------------7------------------14Acid Neutral Base

Acids & Bases

Neutralization: - a reaction between an acid

and a base that produces salt and water

HCl + NaOH H2O + NaCl

Acids & Bases

Acid-Base Titration: - neutralization reaction used

to determine volume & concentration of acids & bases

Acids & Bases

Titration Equation: Na x Va = Nb x Vb

a = acid; b = baseN = normality (concentration)V = volume (ml)
