A buffer solution is prepared by dissolving 1.50g each of benzioc acid C6H5CO2H and sodium benzoate NaC6H5CO2 in 150.0mL of solution.a) What is the pH of this buffer solution?b) Which buffer component must be added and what quantity is needed to change the pH to 4.00?c) What quantity of 2.0M NaOH or 2.0M HCl must be added to the buffer to change the pH to 4.00?
1.248-g sample of limestone rock is pulverized and then treated with 30.00 mL of 1.035 M HCl solution. the excess acid then requires 11.56 mL of 1.010 M NaOH for neutralization.
The ion is stabilized due to the delocalization of the positive charge to the aromatic ring. Draw resonance structures that indicate the stability of this ion.
We are asked to explain the pH and how to find hydrogen ion concentration - Find the pH of an acidic substance of your choice.
