Which would be least likely to completely dissolve in water? hydrochloric acid sulfuric acid nitric acid acetic acid
Answers
Among the four acids mentioned in the question,hydrochloric acid,sulfuric acid ,nitric acid and acetic acid,all the four acids easily dissolve in the water.
But in case of the nitric acid ,it breaks into hydrogen gas and nitrate ion, because nitric acid is a very strong electrolyte chemical compound.
" Strong acids completely dissociates in water. In other words, the completely dissolve in water to produce their respective ions. HCL acid which has the pH range between 0-2, Sulfuric acid which has pH in the range 0- 2.1, and Nitric acid whose pH is 1, are all strong acids.
Hence when they reacts with water which is a base, they almost dissociate to 100%. While acetic acid is the weak acid whose pH is in the range 2.4 to 3.4 cannot dissociate completely in the water."
