What do you mean by solving for the pH?
Do you have the concentration? if YES, you CALCULATE the pH with the relation
pH=-log(c) where c is the value of concentration in mol/L.
ex: c= 3.57x10^(-6)
pH: (-) [LOG] 3.57 [2nd][EE] [(-)] 6 [ ) ]
Here you have 2 change sign key press [(-)]

If you have the pH, and want to calculate the concentration that yields that value of the pH you proceed as follows
c= 10^(-pH)
Ex pH=8.23
c: [2nd][LOG] [(-) 8.23 [)]

Here is a screen capture to show you both calculations

In need step by step on how to enter ph into a ti34 multiview to get concentration.


pH=-log(c)
c=10^(-pH)
c=10^(-8.5)=3.1622 *10^(-9)
You do not need to use the EE key. Use the general power key marked [X^y], or [Y^x] or just [^]
I believe you should familiarize yourself with you calculator. It saves a lot of unnecessary grief.

Find the antilog on the TI-83 Plus for finding pH in chemistry problems


I reccently had the same problem, but I have a Ti-84 Plus,and I am disgusted by how poorly this matter is covered by Texas Intruments. Esp. since the solution is rather simple.

The antilog key is [2nd] [log] or the 10^x. On your screen it should apear as 10^( and then you just input the value that you want to find the antilog of.

When used to solve pH problems remember to input the pH value as a negative number, since pH= -log[H+] then [H+]= antilog(-pH).

Hope that helped))))) ^^
