Calculate the molar concentration of H3O ions and the pH of the following solutions: (a) 25.0 cm3 of 0.144 m HCl(aq) was added to 25.0 cm3 of 0.125 m NaOH(aq), (b) 25.0 cm3 of 0.15 m HCl(aq) was added to 35.0 cm3 of 0.15 m KOH(aq), and (c) 21.2 cm3 of 0.22 m HNO3(aq) was added to 10.0 cm3 of 0.30 m NaOH(aq).

Hi; /c

Molarity is moles of solute over liters of solution. idk if that is what you are talking about, but you can convert moles of solute to grams of solute using dimensional analyzes by using molar mass found on the periodic table.

Hcn is the correct answer leave a good rate and .

The reaction 2kalsi3o8 + 2(h+ + hco3-) + h2o  →  al2si2o5(oh)4 + 2k+ + 2hco3- + 4sio2 shows that feldspar kalsi3o8 is chemically altered by hydrolysis to form chalky-looking clay mineral kaolinite al2si2o5(oh)4. the chemical breakdown of potassium feldspar due to exposure to acidic water results to the mineral binding with the water molecule to become kaolinite with silica and potassium and bicarbonate ions in solution.
