Tech-Acid and Bases

 Really late from this one, but here is my tech lesson on Thursday last week. We got to do a really fun and cool experiment. We learned about pH. We got to test some different liquids with the litmus paper. Lets just say somethings some of the liquids were good. I did this with my bestie Roman and we had a great time. Before I forget we did this experiment with Miss/Mrs Smallwood Can't wait for the next experiment. ENJOY!  

Topic 8-Acid and Bases Question- What is pH? pH is a scale used to specify the acidity or basicity of a solution. Acidic solutions are measured to have lower pH values than basic.  How do you measure pH ? You can measure it with things like litmus paper,measuring systems and much more What is the scale pH is measured on? pH is a measure of how acidic/basic water is. The range goes from 0 - 14. 7 being neutral. What pH level does water have? Is water acid,basic or neutral? Between 6.5 to 8.5. Water is neutral  What is the most acidic pH level? 0 What is the most basic pH level? 14  0-6-acidic 7-neutral  8-14-basic  Note: Blood-7-neutral Coke-3-acidic

Atoms: Simplest format of matter Acids-have more hydrogen ions Bases-have hydroxide ions
