Question about Texas Instruments Office Equipment & Supplies
You should use the equivalence
y=10^(x) is equivalent to x=log(y)
You should not use word that have no meaning. x above is sometimes called antilog, not reverse log.
The relation linkin pH and pOH is as follows
pH+pOH=14, thus pH=14-pOH
Let c[H+] be the concentation (or if you use the hydronium ion, instead of H+ ) c[H3O+] the concentration of hydronium ion)
pOH= 6.95 thus pH=14-6.95 = 7.05
If pH=7.05 the c[H+]= 10 ^(-7.05) =8.9125E(-8)
pH= 10^ [X to the power] [(-)]7.05
The key/buttom to raise to the power is the one to the right of x squared
Hope it helps
