Acids & Bases , p ) A few common Acids What do you notice about the formulas?? sulphuric acid hydrogen cyanide (prussic acid) phosphoric acid nitric acid hydrochloric acid H 2 SO 4 HCN H 3 PO 4 HNO 3 HCl When dissolved in water Acids will form LOTS of ions and VERY LITTLE ions A few common Bases What do you notice about the formulas? white lead carbonate calcium hydroxide glycerine or glycerol sodium hydroxide ammonium hydroxide 2PbCO 3 Pb(OH) 2 Ca(OH) 2 C 3 H 5 (OH) 3 NaOH NH 4 OH When dissolved in water, Bases will form LOTS of ions and VERY LITTLE ions 2) When humans burn fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere. These chemical gases react with the water, oxygen, and other substances in the air to form mild solutions of sulfuric and nitric acids. Google National Geographic Acid Rain and click on the first link, OR, go to: Read through the article and answer the questions below: Why/How is acid rain a problem for animals, plants and eco-systems in general? How could we contribute to reducing acid rain?

Effect on RED Litmus paper: Effect on BLUE Litmus paper: Effect on RED Litmus paper: Effect on BLUE Litmus paper: The reaction that happens between an and substance. The products of which are always: The ph scale: label- Acids, Bases, Strongest Acids, Strongest Bases,. Also Place at least 3 examples (1 example of each of an acidic/basic/neutral substance) on the chart below using p. 429.
4 Name: Date Pd: Identifying Acids & Bases and ph Using Litmus Paper and Universal ph indicator Solution! Directions: You are a chemist working for Williamsburg Science Labs. Your job is to test different classroom and household substances to determine if they are acids and bases. You also want to tell how strong of an acid or base the substance is, to make sure that proper safety warnings and procedures are followed when the substance is in use. You will work in pairs for this lab. PART 1: DETERMINING IF IT S AN ACID, BASE (ALKALINE), OR NEUTRAL USING LITMUS PAPER ***ACIDS*** No effect on red litmus paper; Turns blue litmus paper. (**if it is strong, however it may corrode/ bleach the paper after a few minutes if left to sit) NEUTRAL If neither the red or blue litmus paper change color, the substance is probably. (or very close to it) ***BASES*** Turn red litmus paper ; No effect on blue litmus paper. (**if it s strong, however it may corrode/ bleach the paper after a few minutes if left to sit) Materials: Red & Blue Litmus paper, tweezers, droppers, paper-towels, plastic sheet, various substances to test REMINDERS: WEAR SAFETY GOGGLES DO NOT CONTAMINATE DROPPERS! PART 1 PROCEDURES-LITMUS PAPER: 1) Using tweezers, place one small piece each of red Litmus paper, and blue Litmus paper on a plastic sheet a few centimeters apart. Organize your litmus paper on your plastic sheet as shown to the right (you can place more than 5 if they will fit) 2) Obtain your first substance and use the dropper/pipette to place ONE drop of the substance on your first red and blue litmus papers. DO NOT CONTAMINATE!!!!! Note on your data sheet if the substance caused either of the litmus papers to change color. 3) Test for the substance s actual ph using the directions in the next section. Fill this in on the data collection sheet as well. 4) Put back substance and get your next substance. **You may take up to 2 substances back to your table at a time to save you some trips. 5) Repeat above steps until you have tested all the substances you have time for.
5 PART 2: DETERMINING ACTUAL ph USING UNIVERSAL INDICATOR SOLUTION ***ACIDS*** On a ph scale, Acids have a ph of LESS than to The strongest Acids have a ph closer to The weaker Acids have a ph closer to NEUTRAL On the ph scale, substances have a ph of exactly. ***BASES*** On ph scale, Bases have a ph of MORE than to The strongest Bases have a ph closer to The weaker Bases have a ph closer to GLUE IN YOUR universal ph indicator solution KEY in the space below: Materials: Well plate, Universal ph indicator solution, droppers, various substances to test REMINDERS: WEAR SAFETY GOGGLES DO NOT CONTAMINATE DROPPERS! PART 2 PROCEDURES- Finding the substance s actual ph 1) Using a dropper, place 3-4 drops of the neutral ph indicator solution (should appear green) into each well in the plate as shown to the right 2) Obtain your first substance and use the dropper to place 1-2 drops of the substance into the first well. DO NOT CONTAMINATE!!!!! 3) Observe for a few seconds if the substance has a color change. Compare the color to your universal ph indicator KEY. Figure out which color it matches best and determine the substance s ph. Record this information in your data table. 4) Put back substance and get your next substance.**you may take up to 2 substances back to your table at a time to save you some trips. 5) Repeat above steps until you have tested all the substances you have time for. CLEAN UP AND DO NOT LEAVE TRASH/SUPPLIES OUT! CLEAN UP: Wipe off the small plastic sheet using paper towel-throw paper towel away, being careful not to actually touch the substance with your hands. Rinse hands briefly in sink if you do touch a strong chemical. Wipe off plastic sheet, put back. CLEAN UP ALL TRASH!!!! Dump out well-plate in sink. Leave in bucket in sink to rinse off or wipe off with a wet paper-towel.
6 NAME ETC: DATA SHEET Identifying Acids & Bases and ph Using Litmus Paper and Universal ph indicator Solution! SUBSTANCE NAME BEFORE TESTING!! What do you ESTIMATE it s ph to be? (based on what you know about this substance s other properties) BLUE LITMUS PAPER RESULTS RED LITMUS PAPER RESULTS Actual (approx.) ph (list the # it best matches according to your key) ACID, BASE or NEUTRAL? (circle one, according to your collected data) STRONG or WEAK? (acid or base)
