Hi!
I need to find the pH for a solution with a hydrogen ion concentration of 3.7 x 10 to the -5 M. (the 10 to the -5 part is scientific notation). I also was wondering if anyone knows the ion produced in basic or alkaline solutions? I can't find the answers on wikipedia or any other site...
Thanks in advance,
Jan

pH=-log[H+]
= -log (3.7*10^-5)
= 4.43
The ion in basic solutions is the hydroxide ion or OH-

An acidic solution is one where the concentration of hydrogen ions is greater than the concentration of hydroxide ions. A basic solution has a higher concentration of hydroxide ions than hydrogen ions.
pH is defined as the negative logarithm of the hydrogen ion concentration. So, enter the hydrogen ion concentration into your calculator, take the log of that and then change the sign. That gives you the pH.

pH= -log (H+)
ion produced depends on the reaction. a product of an acid/base reaction will result in a salt compount.

An acid + metal > metal salt + hydrogen
Hey its like 5 or 6 of them t hat i can't remember right now

Find pH using the equation: pH = -lg (conc of H+)
I presume you wan to find the concentration of OH- (basic).
The relationship btw pH and pOH is: pH + pOH = 14
You can then find pOH, then use basic mathematical knowledge, find concentration of OH-: [OH-] = 10^(pOH)
