Measure of pH of the acidic solution is: pH= -log (H3O+)
What is the pH of a 0.062M HBr aqueous solution that completely dissociates in water? (with correct decimal places, sig figs, and logarithms and the molarity given)
When using pH paper to determine the pH of a solution in a 100mL beaker, which method is appropriate?
Galvanic cell consists from CO/CO2+ standard electr0de and NI/NI2+ ELECTRODE. At what concentration of nicle electrolyte the theoretical
Calculate the concentrations of H3O+ and the pH of each acidic solution. Since HCl is a monoprotic acid (an acid that donates only one proton or hydrogen atom permolecule to an aqueous solution), the H3O+ concentration is equivalent to the HCl mol..
Calculate the molar heat of neutralization assuming the specific heat of the solution is the same as for water
