write a hypothesis about the ph level of common household solutions based on what you know about their physical and chemical properties. use the format of \if... then... because...\ and be sure to answer the lesson question \how is ph used to determine if a solution is acidic or basic?\
Answer
Brief Explanations:
A hypothesis is an educated - guess. The pH scale ranges from 0 - 14, with values below 7 being acidic, 7 being neutral, and above 7 being basic. We can make a hypothesis based on common knowledge of household substances' properties. For example, lemon juice is known to be sour which is a characteristic of acids.
Answer:
If a household solution is lemon juice, then its pH level will be less than 7 because lemon juice contains citric acid which releases hydrogen ions in solution, making it acidic. pH is used to determine if a solution is acidic or basic by comparing its pH value to 7. If pH < 7, the solution is acidic; if pH = 7, the solution is neutral; if pH > 7, the solution is basic.
