●When I started with my first experiment I started with a quarter of a Tums and there was no effect. Then, I tried ½ and the PH changed into 3. So after I saw there were slow effects I decided to put 1 whole Tums. Soon after tiny bubbles appeared, but the PH was unchanged. After that the bubbles appeared,I put in 4 more Tums. After the fourth Tums, the PH started to change to 4. I decided to put in 2 more. After the seventh Tums, the PH started to change to neutral which means there was less acidic reaction. The formula became like a soda because when I opened it there was a fizz. When I started I accidently dropped a PH stick it landed at the BOTTOM after the fourth Tums it was in the MIDDLE and by the six Tums it floated to the TOP.

For my 2nd trial I used the following materials :

●500mL- Distilled water ; 250mL- Hydrochloric Acid/HCI; 1½ Himalayan salt

I took 1 tbsp of my new formula and 1 Tum there was a bubbly reaction. I took 4 tbsp of my formula and added ¼ of a tum there was a little reaction. I decide to put ½ of a Tum-- it did not turn blue like the last one. 2 Tums later it turned neutral. This experiment was successful when I put 1 Tums-- its started to change but the PH was still the same. After 7 Tums there was a slight change. After 22 Tums the pH changed and I observed that the solution had a lot of fizz. The reaction in the first trial was faster because I used more hydrochloric acid.

Research Plan:

I will research the affects of fatty foods on reflux and heartburn.


1.Rinse the 2 L bottle thoroughly with water, but do not use soap. 2.Using a measuring cup, carefully fill the 2 L bottle with 1.8 L (1800 mL) of distilled water. You may want to use a clean plastic funnel for this step. 3.To the 2 L bottle, carefully add 200 mL of 0.1 M (also called "0.1 N") hydrochloric acid. You may want to use a clean plastic funnel for this step. Carefully remove the lid on the 2 L bottle, and measure the pH of the solution using a pH measuring stick 4..Cut a TUMS tablet into equal-sized quarters with the help of an adult. Add ¼ of a powdered TUMS tablet to the 2 L bottle of artificial stomach acid you just made. 2.Screw the lid of the 2 L bottle on securely, and very carefully turn the bottle upside down repeatedly until the contents appear mostly dissolved. 3.Measure the pH with the pH measuring stick. Record the total amount of TUMS® tablets added so far and the corresponding pH in the table in your lab notebook.

Repeat steps 2 to 4 until the pH is approximately 4
