Pour 1-2 ml of potassium silicate solution into two test tubes. Pour 1-2 ml of hydrochloric acid into the first tube, and the same amount of acetic acid solution into the second. What do you observe? Write the reaction equations in molecular and ionic forms
In both cases, precipitation is observed.
A) K2SiO3 + 2 HCl = 2 KCL + H2SiO3
2 K (+) + SiO3 (2-) + 2 H (+) + 2 Cl (-) = 2 K (+) + 2 Cl (-) + H2SiO3
SiO3 (2-) + 2 H (+) = H2SiO3
B) K2SiO3 + 2 CH3COOH = 2 CH3COOK + H2SiO3
2 K (+) + SiO3 (2-) + 2 CH3COO (-) + 2 H (+) = 2 K (+) +2 CH3COO (-) + H2SiO3
SiO3 (2-) + 2 H (+) = H2SiO3
