Acids Alkali's Bases Flashcards
What does an acid produce in water
H+ ions
What do alkalis produce in water
OH- ions
What are bases
Bases are the soluble and insoluble substances that react with acids in a netralisation reaction to form a salt+water,Metal Carbonates and Oxides
What are 2 examples of alkalis
Metal hydroxide and ammonia
What are alkalis
Soluble bases
What is a Neutral pH
A pH of 7
What is 1 on the pH scale classed as,acid or alkali
Acid
What is 9 on the pH scale classed as,Acid or Alkali
Alkali
Is the reaction quicker or slower the more reactive a metal is
Quicker the more reactive a metal is
What determines whether an acid is weak or strong
Whether or not it fully dissociates in water
What acid fully dissociates in water,strong or weak
Strong
Does a weak acid fully dissacociate in water
No it is a reversible reaction
Is the strength of an acid the same as acid concentration?
No
What does the concentration of an acid mean
It’s a measure of the number of H+ ions in the solution
Do concentrated acids have their molucules mixed with lots of water
No they have little to no water molecules mixed in
What are dilute acids
Acids that have lots of water molecules mixed in with them
What are indicators
Substances that change a certain colour when they are added to a substance
