Question 978572: Chemists use the pH (hydrogen potential) of a solution to measure its acidity or basicity. The pH is given by the formula shown below, where [H+] is the concentration of hydrogen ions in moles per liter.
pH = −log[H+]
Most common solutions have pH ranges between 1 and 14. What values of [H+] are associated with these extremes? (If you enter your answers in scientific notation, round the decimal value to two decimal places. Use equivalent rounding if you do not enter your answers in scientific notation.)
pH 1
pH 14

Rely strictly on the definition which you have.

pH=1
-log%2810%2CH%29=1, where H is meant to represent [H+] for hydronium ion concentration in moles per liter.
log%2810%2CH%29=-1
Put into exponential form,
H=10%5E%28-1%29

That means [H+]=0.10


For pH 14, you should have no trouble finding that [H+]=1*10^(-14) or 1%2A10%5E%28-14%29.
