1. Acids + Alkalis Flashcards
what is produced when a non metal oxide is dissolved in water
acid
what is acid rain
non metal oxide gases mixing with rain
what is CH3COOH
ethanoic acid
what is produced when a metal oxide or a metal hydroxide is dissolved in water
an alkali
what happens to the pH of the water when metal oxides or hydroxides that are insoluble are added
the metal oxide/hydroxide cannot dissolve and therefore cannot change the pH of the water. it’s like putting a lego brick in water, it can’t dissolve therefore the water stays the same Nothing
what is the equation of the breakdown of water molecules into ions
H2O ↔️ H+ and OH-
the reaction can go both ways
what is the concentration of ions in an acid
H+ > OH-
what is the ion concentration in an alkali
H+ < OH-
what is the ion concentration in a neutral (water)
H+ = OH-
what happens to the pH when acid is diluted
it goes up
what happens to the pH when alkali is diluted
it goes down
what happens to the pH when a neutral is diluted
it stays the same
What is HCl?
Hydrochloric Acid
What is HNO3
Nitric Acid
What is H2SO4?
Sulfuric acid
