You've sent the image again, so I'll continue with the method for question 5 from where we left off. 5 METHOD (USING UNIVERSAL INDICATOR PAPER) (Continued) Step 4: Stir the bicarbonate of soda and water mixture with a glass rod until the bicarbonate of soda dissolves. Step 5: Dip one strip of universal indicator paper into the bicarbonate of soda solution and compare its color to the pH chart to determine the initial pH. Record this pH. Step 6: Add one dropper/syringe full of white vinegar to the bicarbonate of soda solution. Step 7: Stir the solution thoroughly with the glass rod. Step 8: Dip a new strip of universal indicator paper into the solution and determine the new pH. Record this pH. Step 9: Repeat steps 6-8, adding one dropper/syringe full of white vinegar at a time, until the solution becomes acidic (pH less than 7) or neutral (pH 7). Send me the next one 📸
