Study Notes
Characteristic Properties of Acids and Bases
- Acids turn blue litmus paper red and have a pH < 7.
- Acids react with metals to produce hydrogen gas and are known for their corrosive nature.
- Bases turn red litmus paper blue and have a pH > 7.
- Bases neutralize acids and also exhibit corrosive properties.
Monobasic vs. Dibasic Acids
- A monobasic acid can donate one H⁺ ion, while a dibasic acid can donate two H⁺ ions.
pH Value Significance
- A pH value below 7 indicates acidity, while above 7 indicates basicity; a pH of 7 is considered neutral.
Role of Litmus
- Litmus paper serves as an indicator, changing color to red in acidic solutions and blue in basic solutions.
Arrhenius Acid and Base Definitions
- Arrhenius acid: Dissociates in water to form hydrogen ions (H⁺).
- Arrhenius base: Dissociates in water to produce hydroxide ions (OH⁻).
Conductivity of Strong Acids
- Strong acids dissociate in water to produce hydrogen ions and anions, allowing them to conduct electricity effectively.
Limitations of the Arrhenius Theory
- The Arrhenius theory is limited to reactions in aqueous solutions and does not account for substances that show amphoteric behavior.
Water's Role in Acidity
- Water is crucial for acids to exhibit acidic properties, enabling the dissociation of acids into hydrogen ions.
Products of Neutralization
- Neutralization involves a reaction between an acid and a base, yielding salt and water.
Conductivity of Weak vs. Strong Acids/Bases
- Weak acids and bases are poor electrical conductors, whereas strong acids and bases are good conductors.
Conductivity of Acids in Water
- Acids conduct electricity in water by dissociating to form hydrogen ions, which facilitate conductivity.
Sodium Hydroxide as a Strong Base
- Sodium hydroxide is considered a strong base because it fully dissociates in water, generating hydroxide ions.
Bronsted-Lowry Acid Definition
- In the Bronsted-Lowry theory, an acid is defined as a proton donor.
Strong vs. Weak Acids in Bronsted-Lowry Terms
- A strong acid is an effective proton donor, while a weak acid does not donate protons readily.
Bronsted-Lowry Base Definition
- A base, according to Bronsted-Lowry, is a proton acceptor.
Strong vs. Weak Bronsted-Lowry Bases
- A strong Bronsted-Lowry base is efficient in accepting protons, in contrast to a weak base which is not.
Conjugate Pairs Definition
- A conjugate pair consists of an acid and its corresponding base that differ by a single proton.
Conjugate Acid and Base Examples
- The conjugate base of acetic acid (CH₃COOH) is acetate (CH₃OO⁻).
- The conjugate acid of the hydrogen phosphate ion (HPO₄²⁻) is the dihydrogen phosphate ion (H₂PO₄⁻).
Definitions of Conjugate Acid and Base
- A conjugate acid is a species formed when a base gains a proton.
- A conjugate base results from an acid donating a proton.
