What definition best describes acid?
A substance in a solution that releases hydrogen ions and lowers the pH APEX
What substance releases positive hydrogen ions in water?
An acidic substance releases positive hydrogen ions (H+) in water. These substances are called acids and are commonly found in items such as citrus fruits, vinegar, and battery acid. The release of hydrogen ions is what gives acidic substances their sour taste and ability to corrode certain materials.
What are Arrhenius' definitions for acid and base?
Acids are substances which produce hydrogen ionsin solution.Bases are substances which produce hydroxide ionsin solution.
What is hydrogen ion donor?
An acid is a proton (hydrogen ion) donor.A substance or compound that gives up or transfers a hydrogen atom to another substance is know as an hydrogen-ion donor. Hydroxide ions are still bases - they accept hydrogen ions from acids and form water
What makes acid acidic?
An acid is a substance that releases hydrogen ions, H+, in an aqueous (water) solution, or a substance that gives up a hydrogen ion to another molecule or ion depending on which definition you use.
A substance that releases hydrogen ions in water is a base yes or no?
Electrolytes that release ions that combine with hydrogen atoms are called bases.
What is a substance that releases hydrogen ions when mixed with water?
An acid.
What definition best describes and acid?

What best describes a buffer?
A buffer is a substance in a solution that releases and captures hydrogen ions, keeping the pH the same.Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not changeA buffer resists change in pH by accepting hydrogen ions when acids are added to the solution and donating hydrogen ions when bases are added.

What is a substance that releases hydroxyl ions when dissolved in water?
This substance is a base.
Water is considered an acid because it releases hydrogen ions?
Water has a neutral PH value of 7 and is neither acid or base (alkaline). Since water can be represented by HOH, if we try ro argue that water is ab acid because it releases hydrogen ions, we can also argue that water is a base because it releases OH ions.
