You prefer an acidic pH cleaner, your friend likes to use a product that contains a strong base. The two of you decide to mix the two products, to see if their powers combined make an even BETTER cleaning solution. What is most likely to happen?
The two products will combine to make an even stronger cleaning solution
The two products will mix and take on the pH of whatever the stronger product is
Nothing, acids and bases do not mix
The two products will react to create an arrhenius acid
The two products will neutralize each other, making a useless solution of salt water and possibly deadly gas
