Question

Acid-Base Definitions Select the observable properties of acids. produces color change in indicators bitter taste pHgt 7 sour taste electrolyte react with metals to produce H2 pHlt 7

Answer 1

produces color change in indicators, sour taste, reacts with metals to produce H2, pH

Answer 2

Acids are substances that can donate a proton (H+) to another substance. They have certain observable properties that can be used to identify them. These properties include:1. Producing a color change in indicators: Acids change the color of acid-base indicators. For example, they turn blue litmus paper red.2. Bitter taste: Acids have a sour taste, not a bitter taste. The bitter taste is more characteristic of bases.3. pH less than 7: The pH scale ranges from 0 to 14, with 7 being neutral. Acids have a pH less than 7.4. Sour taste: Acids have a sour taste. This is one of the characteristic properties of acids.5. Reacting with metals to produce H2: Acids react with certain metals to produce hydrogen gas (H2).6. Electrolyte: Acids can dissociate in water to produce ions, making them electrolytes. However, this is not an observable property like the others listed.The incorrect options are "bitter taste" and "pH > 7". Bases, not acids, have a bitter taste and a pH greater than 7.
