Step 1:I'll solve this problem step by step, explaining the chemical properties of bleach:
Step 2:: Identify the Chemical Composition of Bleach
Bleach is typically sodium hypochlorite ($$NaClO$$), which is a basic solution.
It is commonly used as a cleaning and disinfecting agent.
Step 3:: Understand the Dissociation of Sodium Hypochlorite
NaClO \rightarrow Na^{+} + ClO^{-}
When dissolved in water, sodium hypochlorite dissociates into sodium and hypochlorite ions:
Step 4:: Analyze the Hypochlorite Ion's Behavior
ClO^{-} + H_{2}O \rightarrow HClO + OH^{-}
It can accept a proton (H^{+}) from water, which increases the concentration of hydroxide ions (OH^{-}):
Step 5:: Determine pH Characteristics
Because the solution produces hydroxide ions, bleach has a basic pH, typically around 11 - 13, which is significantly above the neutral pH of 7.
Final Answer
Bleach is a base due to the basic nature of the hypochlorite ion, which increases hydroxide ion concentration when dissolved in water.
