Study Notes
Acid-Metal Reactions
- Acids react with metals to produce a salt and hydrogen gas.
- The specific salt formed depends on the acid and metal reacting.
- A table of examples shows the various salts produced by different reactions.
Testing for Hydrogen Gas
- Detailed instructions on how to test for the presence of hydrogen gas in a chemical reaction are not provided in the text.
Acids and Carbonates
- Acids react with carbonates to produce carbon dioxide gas, water, and a salt
- Carbon dioxide turns limewater cloudy
- The general word equation for this reaction is: Carbonate + Acid → Salt + Water + Carbon Dioxide
- Specific examples of this reaction, including word and symbol equations, are provided.
Metal Carbonates
- Metal carbonates are salts of carbonic acid.
- Carbonic acid is a weak acid that can be replaced by stronger acids.
- Carbonic acid readily decomposes into water and carbon dioxide.
- Metal carbonates react with acids to produce salt, water, and carbon dioxide gas.
- Examples of metal carbonate reactions include copper carbonate reacting with sulfuric acid to produce copper(II) sulfate, water, and carbon dioxide. Another example is calcium carbonate reacting with hydrochloric acid to form calcium chloride, water, and carbon dioxide.
Neutralisation
- The opposite of an acid is a base
- Alkalis are soluble bases
- Acidity is measured on the pH scale, ranging from 1 to 14
- A reaction between an acid and an alkali produces a salt and water
- Acids and alkalis can be strong or weak.
- The pH of a solution determines its acidity or alkalinity, neutral is pH7
- Various examples of acids and alkalis are given.
pH Scale
- The pH scale measures acidity or alkalinity
- Universal Indicator changes colors depending on the pH
- Seven is neutral on the pH scale.
- Below seven is acidic and above seven is alkaline
Uses of Neutralization
- Neutralisation is used to treat acidity (e.g., indigestion)
- Neutralisation is used to treat acidic or basic soils
- Neutralisation is used to treat tooth decay
Recording Observations
- Instructions on how to do an experiment on reacting metals and acids and collecting observations; this includes a table to record the observations
Chemical Reactions: Reactants and Products
- Reactants are the initial substances in a chemical reaction
- Products are the substances formed by the chemical reaction.
- Equations can be either decomposition or combination reactions
Naming Salts
- The name of the salt is formed by combining the name of the metal with the name of the acid.
- The ending of the name of the salt part of the acid e.g. chlorides, sulfates, nitrates, ethanoate
Homework
- Complete word equations for different metal and acid reactions
Reactivity Patterns
- The reactivity order of metals with acids follows a pattern in the periodic table
