produces color change in indicators, bitter taste, pH>7, electrolyte
Explicación
Bases have certain observable properties. They can produce a color change in indicators, such as turning red litmus paper blue. They have a bitter taste. They have a pH greater than 7, which indicates they are alkaline. They do not have a sour taste, which is a characteristic of acids. They can act as electrolytes, which means they can conduct electricity when dissolved in water. They do not react with metals to produce hydrogen gas (H2), this is a characteristic of acids. Lastly, they do not have a pH less than 7, this is a characteristic of acids.
