Answer:
The Correct Answer is pH = 8.3 and 4.4
Explanation:
pH - pH is a scale used in chemistry to describe the acidity or basicity of an aqueous solution. The pH of acidic solutions is lower than that of basic or alkaline solutions.
Titration to pH 8.3 (decolorization of the phenolphthalein indicator) implies complete neutralisation of OH and half of CO3(2-), whereas titration to pH 4.4 (a fast change from yellow to pink of the methyl orange indicator) indicates alkalinity due to OH, CO3-, and HCO3-.
The reaction is given below:
