#19 Record the total volume of NaOH at the equivalence point. Hint: Equivalence point in this titration refers to the the point when the all the acid is neutralized by the base added (similar to end-point of a titration). Refer to this video. The equivalence point in the S- shaped plot will be point corresponding to steepest rise in the pH. Locate it from the data points on the S-shaped plot and report the corresponding volume of NaOH. 4.2 ⒸmL NAOH Answer format: Number: Round to: 1 decimal places. # 20 Upload your graph from the previous question. Take a snip* of your graph and drag-n-drop it into the box below. Only include the graph in the snip, not the data or anything else. Make sure the axes are labelled along with units wherever appropriate. The file must be in a JPEG or PNG format. HEIC files, the default image file used in iPhones and iPads, cannot be opened by the instructor. *A snip is a screenshot of just a portion of your screen. For PCs, press: windows key + shift + s. Then use the + pointer to select the area or the screen with your graph. For MACs the shortcut is shift + command + 4. If you are using another device you can google " [insert device name] snip shortcut" to find the snip tool.
