1.) 4.00 g of NaOH are dissolved in water to make 5.00 L of solution. What is the concentration of hydronium ions, [H3O+], in this solution? Express your answer with the appropriate units. 2.) If you wanted to determine how much KOH (potassium hydroxide; a strong base) was dissolved in water, you could titrate it with a known amount of KHP (potassium hydrogen phthalate; a weak acid) until a color change indicates that the base is completely neutralized. The molecular...
