Question

abel the ph scale below using the terms from the provided word bank.
word bank: 140 7 neutral base acid alkaline

1. determine whether the following solutions are acidic, basic, or neutral:

a. water has a ph of 7:
b. orange soda has a ph of 5.6:
c. bleach has a ph of 9:
d. human blood has a ph of 7.4:
e. milk has a ph of 8:

Explanation:

• For the pH scale: The middle mark is labeled with \(7\) (neutral). The far - right mark is labeled with \(14\) (base/alkaline).
• For the solutions:
• Water with pH \(7\) is neutral as pH \( = 7\) represents a neutral solution.
• Orange soda with pH \(5.6\) (\(<7\)) is acidic.
• Bleach with pH \(9\) (\(>7\)) is basic/alkaline.
• Human blood with pH \(7.4\) (\(>7\)) is basic/alkaline.
• Milk with pH \(8\) (\(>7\)) is basic/alkaline.

Answer:

1. pH scale: Middle mark: \(7\) (neutral); Far - right mark: \(14\) (base/alkaline)

2.

• a. neutral
• b. acidic
• c. basic/alkaline
• d. basic/alkaline
