Acid-Base Reactions

Acids react with

• water to produce bases and salts
• salts to produce bases and water
• neither bases, salts nor water
• bases to produce salts and water

What is a titration?

• when the moles of hydrogen ions is equal to the moles of hydroxide ions

• adding a known amount of solution of known concentration to determine the concentration of an unknown

• reaction in which an acid and a base react in an aqueous solution to produce a salt and water

• the extent of ionization of an acid or base

What completely ionizes in solution?

• Weak acids

• Strong acids

• Strong Salts

• Neutral salts

If an acid is combined with a base of equal strength, the result will most likely be

• a neutral solution.
• a stronger acid.
• impossible to tell without testing the pH.
• a stronger base

pH is a measure of

• the hydronium ion concentration
• the hydroxide ion concentration
• dissociation
• ionization

A strong base is defined as a substance which

• donates protons very strongly.
• accepts protons very strongly.
• form many hydronium ions.
• dissociates almost completely.

In a titration, the __________ is the point at which the indicator changes color and stays that way.

• standard point
• pH point
• acid point
• end point

HCl +H2O ------> H3O+   +   Cl-  is an example of _____________________.

• ionization of an acid
