According to arrhenius theory, acids are those which when dissolved in water, they release h -positive ions or the protons in water.
00:13
And bases are those which when dissolved in water, they release o -h -negative or hydroxyl ions in water.
00:24
So here in the given options we have calcium hydroxide, c -a -o -h -o -h -w -w -2 -e.
00:32
This calcium hydroxide when this is dissolved in water, so it will dissociate to form calcium ions, ca2 positive and oh negative ions.
00:47
So since here the calcium hydroxide releases the oh negative ions, so that's why this is a base.
00:55
So since caoh hold twice dissociate in the base, water to release oh negative ions it is a arrainius base now apply this theory on the another options also suppose we have nh3 so this nh3 when it is dissolved in water so this leads to formation of nh4 positive ion and oh negative ion.
02:02
So this is also a rhenous base...
