A large amount of heat is released when strong acids are mixed with water. Adding more acid releases more heat. If you add water to acid, you form an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it.
CaO+2hcl----->CaCl2+H2O
MgSO4+ H2O + CO2
Sulphurous acid is formed H2O + SO2 ----> H2SO3
ZnCO3 + 2HCl = ZnCl2 + H2O +CO2
Little Johnny is no more, What he thought was H2O Was H2 SO4.
H2O (water) is neutral, neither an acid nor an alkali.
In the reaction, HBr donates a proton (H+) to H2O, making HBr the acid and H2O the base. The resulting products are Br- (conjugate base of HBr) and H3O+ (conjugate acid of H2O).
When potassium hydroxide (KOH) reacts with nitric acid (HNO3), potassium nitrate (KNO3) and water (H2O) are formed. The overall reaction can be represented as: KOH + HNO3 → KNO3 + H2O
When you mix water (H2O) and acetic acid, the acetic acid will dissolve in the water to form a solution. Acetic acid is a weak acid and will partially dissociate into hydrogen ions (H+) and acetate ions (CH3COO-) in the water. This will result in a slightly acidic solution.
When sulfur dioxide mixes with water, it forms sulfurous acid (H2SO3). This reaction is reversible, as sulfurous acid can also release sulfur dioxide and water. The formation of sulfurous acid can contribute to acid rain formation when sulfur dioxide is released into the atmosphere.
The conjugate acid of H2O is H3O+ (hydronium ion). When an acid donates a proton, it forms its conjugate base, and when a base accepts a proton, it forms its conjugate acid.
The conjugate acid of the base H2O is the hydronium ion (H3O+), which forms when H2O accepts a proton (H+).
