a) Base b) Synthetic indicator c) Ruminant
Answers
Answer:
a) Examples of bases are the hydroxides of the alkali and alkaline earth metals (sodium, calcium, etc.) and the water solutions of ammonia or its organic derivatives (amines). Such substances produce hydroxide ions (OH-) in water solutions (see Arrhenius theory).
b)Examples of synthetic indicators are: Phenolphthalein: Phenolphthalein is a synthetic indicator which is colourless in acidic medium but gives pink colour in basic medium. ... Methyl orange: The colour of methyl orange in acidic medium is red and in basic medium, its colour changes to yellow.
c) Examples of Ruminant are cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own.
