What is the Arrhenius definition of a base? A substance that increases H3O+ concentration when it is dissolved in water. A substance that increases OH– concentration when it is dissolved in water. A compound that donates protons. A compound that accepts protons
Answer : The correct option is A substance that increases [tex]OH^-[/tex] concentration when it is dissolved in water.
Explanation :
Arrhenius Definitions :
Arrhenius Acid : It increases the concentration of hydronium ion [tex](H_3O^+)[/tex] in an aqueous solution. In other words, a substance dissociates in water to form [tex]H^+[/tex] ion.
Arrhenius Base : It increases the concentration of hydroxide ion [tex](OH^-)[/tex] in an aqueous solution. In other words, a substance dissociates in water to form [tex]OH^-[/tex] ion.
