What is the pH of a solution that has a hydroxide concentration of 1.9 X 10-5 M? What is the pH of a 0.056 M solution of H2SO4? H2SO4 is a strong acid. Calculate the pH of a 0.50 M solution of Sr(OH)2. Sr(OH)2 is a strong base. Mylanta liquid has 200 mg of Al(OH)3 and 200 mg of Mg(OH)2 per teaspoonful. Write the equation for the neutralization of stomach acid. Assuming both bases are completely soluble in water, calculate...
