Yeah, the first compound they are given is fecl3.
00:04
If you observe this fecl3 is formed by perich hydroxide f .uh3x3, 3hcl.
00:11
If you observe in this one, this is a weak base and this one is a strong acid.
00:17
So the resultant compound is acidic in nature.
00:20
As its acidic in nature, its ph is less than 7.
00:24
Whereas coming to the next one, they are given as ammonium chloride, nh4cl.
00:28
It is formed by a combination of ammonium hydroxide and h4 -o -h and hydrochloric acid.
00:35
Here, hydrochloric acid, whereas ammonium hydroxide is a weak base.
00:39
So the resultant one is also acidic in nature, the ph is less than 7.
00:44
Whereas coming to the third compound, they are given as sodium chloride, n -a -cl.
00:49
It is formed by the combination of sodium hydroxide and hydrochloric acid...
