If acid is added to a solution, then the pH of the solution will go down.
If acid is added to a solution, then the pH of the solution will go down.
To determine which of the options would be a testable hypothesis, we need to understand what a hypothesis is. A hypothesis is a proposed explanation or prediction that can be tested through scientific investigation. It should be measurable, specific, and testable.
1. "Dropping a ball from a height of 10 m will cause it to bounce back up 5 m." - This is a testable hypothesis because it makes a specific prediction about the behavior of the ball when dropped from a certain height.
2. "Plants produce glucose as the end product of photosynthesis." - This is not a hypothesis but a statement of fact. It is not making a specific prediction or providing anything to be tested.
3. "If certain foods are healthy for you, then they should also taste good." - This is not a testable hypothesis because it involves subjective terms like "healthy" and "taste good." What is considered healthy or tastes good can vary from person to person.
4. "If acid is added to a solution, then the pH of the solution will go down." - This is a testable hypothesis because it makes a specific prediction about the relationship between adding acid to a solution and the resulting change in pH.
Therefore, the correct answer is option 4: "If acid is added to a solution, then the pH of the solution will go down."
The testable hypothesis among the given options is:
If acid is added to a solution, then the pH of the solution will go down.
