What happens to the acidity of solutions A and B after dry ice is added? The pH of solution A decreases, and the pH of solution
B increases. The pH of solution A increases, and the pH of solution B decreases. The pH of solution A increases, and the pH of solution B increases. The pH of solution A decreases, and the pH of solution B decreases.
Explanation: its quite simple really, you need to get a periodic table and find the symbol of said elements. Lead is Pb, and carbonate is another word for carbon and oxygen, so it is C and O
