Hypothesis:
I belive that salt does effect the acidicy of water. Related experiments: ~using balanced water to save lives ~to solve the water problem we need to save the energy Related internet searches: ~how do fish live in salt water ~which animals can adjust to salt water Related information: Saltwater is 97 percent of all the water on earth. Freshwater makes up about 2 percent of all water. The other one percent is made up of brackish water, distilled water, etc. Materials: ~a cup of saltwater ~a cup of freshwater ~a cup of distilled water ~a couple phs strips ~a paper to record your discoveries Instructions: Take the ph strip and use it to deterime the acidicy of saltwater, freshwater, and distilled water. Use this data and write it down. The ph strips for the saltwater were much a darker shade of green than the strips for the distilled and fresh water. The distilled water and the freshwater were closest to yellow making them the closest to neutral. Each of the containers carried about the same amount of water. That doesn’t really change anything though because the content is still the same. Distilled water got a ph of 6.5, freshwater was about 7.5, and saltwater, the most acidic of the three, had a ph of 8.5. As I hypothesized the saltwater was the most acidic. The ecosystem and habitiats relate to my question because the world is made up of 75 percent water. Life revolves around water. Where there is water there is life. This is why many people believe that they should look for water on other planets. This water consisted of three main types of water: freshwater, saltwater, and distilled water. Most of it is saltwater, and there are some mixes between some of them. One example of this is brackish water. |
