#### Do basic solutions also have H+(aq) ? Why are they basic ?



Ans: When a base is dissolved in water then it will produce H⁺ ions as wells as OH⁻ ions.
if H⁺ ion concentration is more than OH⁻ ion then the solution is acidic...

#### why are ionic compounds brittle. it is mentioned that they are strongly attached to each other and are hard solids yet it is also written in our book that they are brittle in nature. Can i have a solution to my confusion?



The ionic compounds are very hard and brittle. In ionic compounds  the ions are rigidly held in a lattice because the positive and negative ions are strongly attracted to each other and difficult to separa...

#### On electroplating an article with silver we use sodium argentocyanide or potassium argentocyanide instead of silver nitrate as the deposition of silver is very fast andhence not smooth and uniform.How does use of silver nitrate, increase the speed of deposition?Explain



Ans: Rate of dissociation is high in the case of silver nitrate as it is ionic molecule where as Sodium argentocyanide or potassium argentocyanide is complex molecule. During the dissociation o...
