When salt dissolves in water, the water molecules are attracted by dissolves salt particles. This attraction is called dissociation.
Hope this helps you. Do mark me as brainliest.

1the carrier would be 3 as to the the yes and the no differ from 2 which would mean they are the same, but if you take three , you have more equal signal, giving it a better digital quality
2incorect, primary, and clocks-worth both as well also use binary ode, because they all have a timmid connetion between gavity waves
One way to look at it is to determine whether the compound is acidic or basic. basic compounds will dissolve more easily in acid
A) Al(OH)3 is the hydroxide of a metal and this is basic. hence this will dissolve better in acid than pure water ( in fact Al(OH)3 is amphoteric meaning it can dissolve in both acid and base)
B) BaF2 is the salt of a strong base Ba(OH)2 and weak acid HF, hence the nature of BaF2 is slightly basic, this will dissolve better in acidic solution
C) PbCl2 is the salt of weak base Pb(OH)2 and strong acid HCl, hence the nature of PbCl2 is slightly acidic, it won’t be more soluble in acidic solution
D) Hg2Br2 is the salt of weak base Hg2(OH)2 and strong acid HBr. the nature of Hg2Br2 is acidic hence, it wont dissolve better in acidic solution
E) NiS is the salt of a very weak base Ni(OH)2 hence this NiS will be acidic in nature nd wont dissolve in acidic solution
F) AgI is the salt of a very strong acid HI and weak base AgOH. nature will be acidic and wont dissolve in acidic solution
in conclusion only Al(OH)3 and BaF2 are more soluble in acidic solution than in pure water as both are slightly basic
