Question

Rank the following compounds in order of increasing pH (1 - lowest, to 5 - highest) and label each compound as strong acid, weak acid, neutral, weak base or strong base? potassium hydroxide methylamine hydrobromic acid potassium iodide ascorbic acid

Answer 1

See below...

Explanation:

potassium hydroxide (KOH)
methylamine (`CH_"5"N`)
hydrobromic acid (HBr)
potassium iodide (KI)
ascorbic acid (`C_"6"H_"8"O_"6"`)

• Rank the following compounds in order of increasing pH

KOH - 5
`CH_"5"N` - 4
HBr - 1
KI - 3
`C_"6"H_"8"O_"6"` - 2

• Label each compound as strong acid, weak acid, neutral, weak base or strong base

KOH - strong base
`CH_"5"N` - weak base
HBr - strong acid
KI - neutral
`C_"6"H_"8"O_"6"` - weak acid
