5th period PhET experimental design observations by https://padlet.com/tlchildress/uw9vv7c8t9hu5c98 Write your observations and takeaways from your acids/bases experiment en-us 2021-05-14 14:02:05 UTC 2021-05-14 14:16:43 UTC hello@padlet.com Soap and water is more acidic than just soap by itself, hence diluting some of soaps disinfectant powers. Soap is a basic and adding water to it makes it a weaker base. Adding ½ liter of water to ½ a liter of soap, made the soap 0.33 Ph more of a weaker basic. vpiparia https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524694584 2021-05-14 14:10:18 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524694584 When the pH level of the original substance is alkaline, meaning that it is above the pH level of 7, water will lessen the pH level in the substance. However, if the original substance is on the acidic side of the pH scale, the pH level will rise when water is added to it. https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524695854 2021-05-14 14:10:37 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524695854 Acids have more H3O+ and H+ tlchildress https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524697348 2021-05-14 14:11:00 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524697348 Combining two substances with different pHs will make the solution have a pH level somewhere in between that of the two substances combined to make it. https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524699750 2021-05-14 14:11:35 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524699750 Adding solutions of different pH levels changes the pH level of the water (originally at pH 7). Hand soap and drain cleaner are more alkaline than milk or coffee (more acidic). https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524700020 2021-05-14 14:11:38 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524700020 As water is added to a solution, the pH level of that solution grows closer to 7. This means that the pH levels of acidic solutions increase, while the pH levels of basic solutions decrease. https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524702136 2021-05-14 14:12:09 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524702136 Because water has a pH of 7, it serves as a neutralizer in both basic and acidic substances. https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524712538 2021-05-14 14:14:31 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524712538 1.10 L of water was needed to change 0.10 L of milk at a Ph of 6.5 to a Ph of 6.93. https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524722171 2021-05-14 14:16:43 UTC https://padlet.com/tlchildress/uw9vv7c8t9hu5c98/wish/1524722171
