A substance that yields a cation plus the hydroxyl ion in water is a(n)_____.
<h2>Answer:</h2><h2><u>C.Base</u></h2>
Did you know that a <u>base</u> is a substance that yields a cation plus the hydroxyl in ion water. A <u>hydroxyl ion</u> is a negatively charged molecule made up of one oxygen bonded to one hydrogen.
Hence, a <u>base</u> is a substance that accepts hydrogen ions. A base is also a compound that produces hydroxide ions<u>(OH+)</u> in solutions.
A <u>base</u> forms OH- ions in solution. It has a pH greater than 7.
Mind you all people that the number of <u>hydroxide ions</u> in solution is greater than the number of <u>hydronium ion</u>. Thats all
