SOLVED: A 1.2g sample of a mixture of NaOH and NaCO3 containing incorrect impurities dissolved and titrated cold with 0.1N HCl with phenolphthalein as an indicator. The solution turns colorless after the addition of 30.0 mL of the acid. Methyl orange is then added and 12 mL more of the acid is required before this indicator changes color. What is the percentage of NaOH and Na2CO3 in the sample?

Phenolphthalein works somewhat differently as it is naturally colorless but turns pink in alkaline solutions. The compounds remains colorless throughout the range of acidic pH levels but begins to turn pink at a pH level of 8.2 and continues to a bright purple in stronger alkalines. #uetss #we_make_the_change | UET Science Society

Experiment Breakdown: 1️⃣ The Setup: The bowl contains water mixed with phenolphthalein (a pH indicator). 2️⃣ The Reaction: When the white piece (caustic soda / NaOH) is added, it dissolves in water to form a basic solution. 3️⃣ The Color Change: Phenolphthalein turns bright pink in basic conditions, making the reaction visually striking! ⚠️ Safety Note: Caustic soda is highly corrosive—always handle with care! This experiment should be done under supervision. #ChemicalReaction #BaseIndicator #C
