Question
Chapter 2, Problem 15TYU
Summary Introduction
To determine: Whether it is safe to immerse our hand in water that contains 0.000,000,000,001 g of H+ per liter.
Introduction: Substances have different properties due to their varying chemical nature. On the basis of chemical nature, substances are categorized as acidic, basic, or neutral. The pH is defined as the negative logarithm of hydrogen ion concentration. The pH value of base (alkali) is greater than 7. The pH value of acid is less than 7. The pH 7 is the pH value of neutral solution.

Q4 1mL of the stock solution acetaminophen (1mg/mL) is used for the estimation of PC using n-octanol. After extraction, 0.1mL of the extracted solution was added to 0.9mL of water and 100uL of this solution was loaded in 96 well plate to the absorbance at 260nm. If the observed absorbance of the extraction phase is 0.2 using the following standard curve equation, Calculate the concentration of acetaminophen in aqueous Phase.
Note: If you need the standard curve equation, please make It up because I want to understand the concept.
