PH Paper Lab Report

Background information/Research
PH paper (litmus paper) determines how acidic or how basic a substance is. The ape changes color accordingly to the color code on the pH scale. The pH scale starts from O to 14. The lower the number the more acidic it is. Zero is the most acidic, and 14 is the most basic c while 7 is the neutral number for example water. Examples of an acid Are lemon Juice or multip repose cleaner. Examples of a basic substance Are shampoo or liquid soap. We use pH for the products we use and food that we eat to check if it is safe to use for us humans and not harm us. With PH. Products have become safer and less harmful to our environment and ourselves. Materials Various indicators BRB blue Phew red Met red Methyl blue.
Procedures
- Take 6 indicators that are all different colors.
- Take the 4 unknowns numbered 14.
- Take a watch tray and wash it down before using it.
- Put the indicator that Is numbered 1 in 6 slots on the watch tray. (Only put in one d rope).
- Take each Indicator and put It in 1 slot each, each slot should have a different Indict taro color. (Again only one drop) .
- Record results and observations down on a table. Observe If It changed color If It changed from
- Wash down the watch tray again so you do not mix chemicals, or else your data will be inaccurate.
- Repeat steps 47 for the last 3 unknowns. Results After the LAB I had various different results for each indicator reaction to the unknown. All together I had 24 results, 6 results for each unknown. A couple of the indicators reacted to the unknown differently than the others. They started to change one color, then a bit late r it would change to a different color.
