Acids And Bases Flashcards
What are acids?
Substances that produce hydrogen ions (H+) when dissolved in water
What forms when acids react with metal?
Salt and hydrogen gas
What are bases?
Substances that can accept hydrogen ions
Examples of bases
-metal oxides
-metal hydroxides
What happens when acids and bases react?
Neutralisation
What are the products of a neutralisation?
Salt and water
What do strong acids do it water?
-fully ionise
-releases a high concentration of hydrogen ions
What do weak acids do in water?
-partially ionise
-releases a lower concentration of hydrogen ions
What are alkalis?
Bases that dissolve in water to produce hydroxide ions
3 indicators
-litmus paper
-phenolpthalein
-methyl orange
Strength of an acid or alkali
Degree of ionisation
How can soluble salts be made?
Reacting acids with metals,bases or carbonates
