PoaPpys e aul, owdoes the aikalinity change in the water (increase/ decrease/ no change) and why? 2. [12] If 200 mg of HCl is added to water to achieve a final volume of 1.00 L, what is the final pH? 3. [16] A solution of acetic acid is prepared in water by adding 11.1 g of sodium acetate to a volumetric flask and brining in the volume to 1.0 L with water. The final pH is then adjusted and

Solution

200mg of HCl in 1 L.

Gram molecular weight of HCl= 35.45+1= 36.45 grams

molarity of HCl in solution = (200mg/1L) *(1 mole/36.45g)/1000 =0.005487 M/L

1 mole of HCl produces one mole of H+ ion upon ionization

H+ ion concentration in one litre of solution= 0.005487

pH= -log[H+ ion] = -log[0.005487] = 2.26

pH= 2.26
