6. A scientist conducted the volumetric analysis using both Parts A and B and obtained the following data: 0.4985g KHP (molar mass of 204.23 g/mol ) was titrated to endpoint with 15.05mL of NaOH as in Part A. Then as in Part B, 25.0mL of unknown concentration of HCl was titrated to the endpoint with 21.50mL of NaOH. What is the concentration of HCl

answer; economic order quantity;

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
