Answer:
1.Universal indicator is a mixture of several indicators.
2.By using ph scale we able to know how strong an acid and base is.
3.mineral acids are weak acids.
4.we can add acids or base into water with constant stirring and this process is exothermic.
5.ACIDS-Acids contains H PLUS ions.
ACIDS CONDUCT ELECTRICITY.
MORE H PLUS ION CONCENTRATION MORE STRONG THE ACID IS.
IT TURNS BLUE LITMUS TO RED.
OLFACTORY INDICATORS- THE INDICATORS WHICH CHANGES ITS ODOUR IN ACIDIC AND BASIC MEDIA.
