• • Acids in the lab
  • Dilute acids:
  • Strong
  • chloric acid and nitric
  • acid
  • often mixed with.
  • are
  • water before being put
  • out to use- these are
  • dilute acids.
  • - The bottles of these acids
  • normally have hazard symbols
  • Labelled on them. So, if they
  • come into contact with your
  • Sking it can irritate it.
• • Concentrated acids:
  • -Concentrated acids are
  • More dangerous than
  • dilute acids as they are
  • Strong acids that are mixed

  • Concentrated acids are
  • Corrosive which means tha
  • they can destroy.

  • They can also attack
  • metal
• • Weak acids
  • - Laboratory acids are far
  • too dangerous to taste
  • but you can eat dilute
  • weak acids.
  • - A lot of food contains
  • acids such as: vinegar,
  • which contains ethano ic
  • acids, and Lemon, which has
  • citric acid. These acids are
  • completely safe to eat but
  • they can sting if it gets.

  • Acids have a sour taste.
• • BASES AND ALKAUS 20
  • bases:
  • that neutralise acids. They
  • Bases are substances.
  • are
  • metal oxides,
  • normally
  • metal hydroxides
  • carbonates
  • or metal
  • bases
  • Bases are insoluble
  • -
  • that do dissolve are called
  • alkalis.
• • bases in the Laboratory:
  • Cleaning products often.
  • contain bases Like sodium
  • hydroxide solution.
  • Concentrated alkalis are just
  • as dangerous as concentrated:
  • acids as they can also
  • attack metal and can
  • damage skin when spilled.
• • -Alkalis have a soapy
  • texture. If they come into
  • contact with Skin- make sure to
• • - Concentrated alkalis are
  • corrosive and will be
  • accordingly.

  • Bases react with oils and
  • fats ire drain clean, So
  • house cleaning products
  • often contain alkal's and
  • bases. For example,
  • bleach and drain cleaners.
  • -It is wise to wear gloves
  • When handling these products
  • as they can imitate the
