Acid and base theories
What are two characteristics of acids
Conduct electricity
Change blue litmus to red
Have a sour taste
Corrosive
React with bases to neutralize their properties
React with active metals to liberate hydrogen
How do identify a Brønsted-Lowry acid
If it donates H+ or protons
What numbers are on tree oh scale
0-14
What is a titration used for
A titration is used to find the concentration of an identified analyte
Name a property shared by acids and bases
Conduct electricity
How do you identify a Brønsted-Lowry base
If it accepts H+ or protons
If a substance is 0-6 on the ph scale
Acidic
What is an analyte
An analyte is the solution in a titration problem with an unknown molarity
What is a bases reaction to phenolphthalein
Pink
In HCl + NH3 = Cl + NH4 identify the conjugate acid and base aswell as the Brønsted-Lowry lowery acid and base
HCl + NH3 = Cl + NH4
Acid. Base. Cbase Cacid
If a substance is 8-14 on the oh scale it is
Basic or alkaline
What is a reagent/titrant in a titration problem
The titrant is the solution with a known molarity that will react with the analyte.
What is a acids reaction to phenolphthalein
Colorless
What is a conjugate acid
The product formed when a base gains H+
If a substance is a 7 on the oh scale it is
Neutral
How do you find moles of an analyte
You divide the number of Moles of analyte present by the original volume of analyte
Based on the Arrhenius theory what does an acid do in water
In the Arrhenius theory, an acid dissociates to produce hydrogen ions in water. A base produces hydroxide ions in water. In the Bronsted-Lowry theory, an acid is a proton donor.
What is a conjugate base
The product formed when an acid loses a H+
What formulas are used to calculate PH
Ph= -log(H3O+)
Ph= POh-14
What is the limiting reagent in a titration problem
Find with reactant is consumed first
