Cards (10)

  • Acidic solutions have pH values less than 7.
  • PH paper can’t be used to test for deeply coloured substances
  • Neutralization is a process which one acid and one alkali mix up to produce water and salt
  • Salt is made up by neutralisation and it’s named by the acid’s first name and alkali‘s last name
  • sulphuric acids + sodium hydroxide=water + sodium sulphurate
  • Alkali‘s ph value is higher than 7
  • 7 is the ph value of neutral substances such as distilled water
  • Litmus paper is a paper that changes color when it comes in contact with an acid or alkali.
  • Litmus paper is made from lichen and lichen is a natural combination of algae and fungi etc
  • ph meter is used to measure ph value accurately and ph paper is used to measure ph value roughly , ph meter also shows more digital of number of the ph value instead of just integars
