Hypothesis

I believe the more the PH the more bubbles will form.

Materials

• Mortar and pestle
• 12 mL Distilled water
• 3 100-liter plastic beakers
• 5 mL syringe
• 2 1 mL syringes
• 1.5 mL Hydrogen peroxide
• 1 Paper towel square (for filtration)
• 5 glass test tubes
• Test tube rack or holder
• Small plastic ruler
• Safety glasses

• .2 mL Hydrochloric acid solution pH 2-3
• .2 mL Hydrochloric acid  solution pH 3-4
• .2 mL Sodium hydroxide solution 10
• .2 mL Sodium hydroxide  pH 12
• pH test strips

Procedure

10 ML of water with 5 grams of oat grass

mash those together with the mortar and pestle and filtered it into the beakerAfter

use 1.5 of that solution in each of the five tubes along with .3 of hydrogen peroxide in each tub

.2 of each of the solutions were placed into the separate tubes that were marked for that certain pH

The final step was to measure the change of the different tubes compared to the control

This was done by measuring the height of the bubbles every 5 seconds.

In conclusion

Conclusion

In conclusion the more PH the more it varies and goes up and down. Then when there is less PH the more solid the bubbles become. So my hypothesis was incorrect because I thought the more PH the more bubbles will form but they didn’t the bubbles just went up and down
