Answer 1

QUESTION 1 When we talk about hypertonic solutions, we are saying that the solution is more concentrated than the inside of the cell (or the compartment). Remember that water flows from the lest concentrated side to the most concentrated side. So There is a net flow of water out of the cell. QUESTION 2 pH = -log[H+] pH = -log[10-9] = 9 Note: According to Chegg's guidelines, you have to send just one question. Please, send each question separate so all experts can answer each of your questions. Thank you!
