What is the equation if the product is CaOH+(aq)?
zavuch27 [327]
The product is called carbon monohydroxide (CaOH+) ion. This is the only product if the solution is alkaline. The reactants are calcium (Ca2+) and hydroxide (OH-) ions. If the solution is acidic, hydrogen (H+) ion is also included in the product side of the equation.

Ca2+(aq) + OH-(aq) -> CaOH+(aq)

What is the definition of an Arrhenius acid?
Lorico [155]

Answer:

I <u>think</u> your answer is: C. ("An Arrhenius acid increases [H +] in the solution.")

Explanation:

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H + ); that is, an acid increases the concentration of H + ions in an aqueous solution. This causes the protonation of water, or the creation of the hydronium (H 3 O +) ion.

Hopefully this helps!

Have a great day! ^^
