scenario: you are testing two different household solutions with your cabbage indicator, using the color key to the right.\none solution turns blue. a possible hydrogen ion concentration for this solution is:\n○ 1×10⁻² m\n○ 5×10⁻² m\n○ 5×10⁻⁴ m\n○ 1×10⁻⁸ m

Answer

Explanation:

Step1: Recall cabbage - indicator properties

Cabbage indicator turns blue in basic solutions. Basic solutions have a low hydrogen - ion concentration.

Step2: Analyze the given options

The hydrogen - ion concentration in acidic solutions is high ($1\times10^{-2}\ M$, $5\times10^{-2}\ M$, $5\times10^{-4}\ M$). The lower the hydrogen - ion concentration value, the more basic the solution. Among the options, $1\times10^{-8}\ M$ has the lowest hydrogen - ion concentration.

Answer:

$1\times10^{-8}\ M$
