Mixing concentrated acids or bases with water is a highly endothermic process.
The correct option is B FalseMixing concentrated acids or bases with water is a highly exothermic process as heat is expelled.
when concentrated acid is added to water identify whether the process is exothermic or endothermic ??
"Mixing an acid or base with water results in decrease in the concentration of ions(H3O/OH-) per unit volume"
Acid when mixed with water gives out H+ ions which because they cannot exist alone form H3O ions. Then how does the concentration 'decrease' ?
