Something is wrong with all 7 of these hypothetical responses for acids and bases. Your job is to find the errors and communicate them with your classmates. • Why is the response wrong? . What is the real correct answer? • Using what you actually know about the content, provide the real response that should have been provided. Here are the responses: Student Response # (Student Question Incorrect Response Name) #1 (Azzarako) Is a solution with a pOH of 4.25 an acid or a base? "This is an acid because it's under 7" # 2 (Hildaflut) The hydrogen ion concentration for a solution with a pH of 12.5 is "1.5 M" # 3 (Jillanofer) TRUE or FALSE: Water is neutral, so it can never act as an acid nor a base "TRUE.
