Do basic solutions also have `H^+`(aq) ions? If yes , then why are the basic?

How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it in the same way? If not, then how are these transported across the membrane?

What effect does the concentration of H^+ (aq) ions have on the nature of the solution?

You have two solutions, A and B. The ph of solution A is 6 and the ph solution B is 8. Which solution has more hydrogen ion concentration? Which of this is acidic and which one is basic?

Two vessels have the same base area but different shapes. The first vessel takes twice the volume of water that the second vessel requires to fill upto a particular common height. Is the force exerted by the water on the base of the vessel the same in the two cases? If so, why do the vessels filled with water to that same height give different readings on a weighing scale?

What is the colour of the litmus solution when it is neither acidic nor basic?

Why do HCl, HNO_3 , etc. show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?

Explain the folloiwng facts: Among lanthanoids Ln(III)compound are predominant, However, occasionally in solutions or in solid compounds, +2 and +4 ions are also obtained.
