Results

Plant	Liquid	pH Value	Plant Appearance (Initially)	Plant Appearance (After 3 Days)
1	Dilute Hydrochloric Acid	2.1	Whole and healthy green leaves, clumps of roots and root hairs	Roots turned red and spread out. Plant wilted. Size of the leaves remained same.
2	Distilled Water	5.8	Whole and healthy green leaves, clumps of roots and root hairs	Healthy plant. Roots remained in clumps and leaves were whole and green. Size of the leaves remained same.
3	Tap Water	7.0	Whole and healthy green leaves, clumps of roots and root hairs	Somewhat healthy plant. Roots remained in clumps, but leaves had holes. Size of the leaves remained same.
4	Toothpaste Mixture	10.2	Whole and healthy green leaves, clumps of roots and root hairs	Plant wilted. Roots were in clumps, but had turned greenish-brown. Leaves had shrunk.
5	Dilute Sodium Hydroxide	14.0	Whole and healthy green leaves, clumps of roots and root hairs	Plant wilted. Leaves shrunk while stem fattened, and roots turned reddish.
