This will only increase with increase in temperature or decrease with decreasing temperature. This does not depend on the concentration of this guy, nor on this guy. Now, if our hydronium concentration is greater than 1.0 times ten to negative seven, that means our solution is acidic. If it's less than 1.0
times ten to seven, it's basic. Likewise, if our hydroxide concentration is less than 1.0 times six, negative seven, it's an acidic solution. If it's more than 1.0 times six mega seven, it's a basic solution.
