Summary:
        Any solution with a PH level of 7 is a solution that is neutral like water. When a solution is acidic it creates hydrogen ions and makes it lower on the PH scale like citric acid and sour candies. When a solution is a base it creates hydroxide ions and makes it higher on the PH scale like soap. To test if a solution is acidic or if it is basic you can put a piece of litmus paper and seeing if it turns a red or a blue color, if it turns red that means the solution is acidic and if it turns blue that means the solution is basic. Your pee is slightly acidic and see water is slightly basic but surprisingly is is safer to drink your own pee rather then drink sea water. When something is more concentrated it means that there is more acid or base dissolved into the solution and when it is diluted it is the opposite.

S&EP:SP3: Planning and carrying out investigations:
        I did an experiment to see how bases and acids can be identified by color by using cabbage juice, an acidic and a basic solution. What we had to do was take the neutral cabbage juice and put them into 12 different tester cups. Then we took the two solutions and made them more concentrated by adding more acid or base to the solution each drop that we added to each cup. We saw that when we had an acidic solution it turned from the basic purple to a light pink to a darker pink and closer and closer to red. When we added the basic solution it made it like a teal and dark green to more of a lime green color. We also compared the colors to their PH levels.

XCC: Structure and Function:
        When something is concentrated and it is very acidic it makes it great for doing things like removing rust from metal to make it more clean and look better. When something is concentrate and it is very basic it makes it good for cleaning laundry and to make it brighter like bleach. The bleach is very concentrated and is higher on the PH scale to make it so that it can easily remove the stains off of your white shirt. The rust removing solution is very concentrate and acidic to make it better remove all of the rust off of the metal where you do not want the rust. Neutral things like water are good so that we can drink it and stay hydrated without having it be acidic or basic.
