Web1. Roughly chop your red cabbage and place it into a large container. 2. Bring your water to a boil and pour it into the container full of cabbage. Use Caution. 3. Stir until water changes color and strain out the liquid into another large container. 4. Wait until liquid is cooled to room temperature. 5. WebYou can also make your own pH indicator strips, like you see lifeguards using to test the pH of pool water. To do this, soak some coffee filter paper in concentrated cabbage juice. Remove the paper from the cabbage juice and hang it up by a clothespin to dry. Cut the dried paper into thin strips. Dip the strips into various liquids to test ... hide crafting gear

WebSep 20, 2015 · Let’s say you test a liquid that reads at a level 4 pH. Is that liquid acidic or alkaline? How about if the liquid turns out to be a level 12 pH. Is that liquid acidic or … WebMar 15, 2024 · Recall that the pH of a buffer solution is given by the Henderson-Hasselbach approximation: pH = pKa + log[A −] [HA] Because [HA] = [A −], the pH of this buffer solution equals the value of pK a for the unknown acid. Thus we can use the measured pH of this buffer solution to determine the value of pK a for our unknown acid. OPTIONAL Webof water has a large impact on the pH. 2. A difference in 1 unit is a 10X difference in concentration For example; a liquid with pH of 3 is 10X more acidic than a liquid with a pH of 4. Therefore, a liquid with a pH of 3 is stronger. 3.
