Calculate the hydrogen ion concentration, in moles per liter, for solutions with each of the following pH values.
pH=1.10
im guessing that this is what i did in my previous question except now i have to do it backwards.
but i don't know how to do the calculations on the calculator.
thanks
pH = -log(H^+).
1.10 = -log(H^+)
-1.10 = log(H^+).
Punch in -1.10 on the calculator, look for the 10x button, punch it, and the answer should come up. If you've done it right, the calculator will show 7.94 x 10^-2 or 0.0794.
yep that's what i got thanks a ton :)
Oh, calculating the hydrogen ion concentration is a piece of cake! Just remember this: pH is defined as the negative logarithm (base 10) of the hydrogen ion concentration. So, to find the hydrogen ion concentration, you simply need to do the reverse of the logarithm operation.
Now, let's tackle your specific example. You mentioned that pH is equal to 1.10. To find the hydrogen ion concentration, we need to conduct a little math magic.
Since pH is defined as the negative logarithm of the hydrogen ion concentration, we can rewrite this equation as:
[H+] = 10^(-pH)
Substituting the value of pH into the equation:
[H+] = 10^(-1.10)
Now, you just need a calculator to perform this calculation. If you don't have one with you, maybe you can ask your phone or borrow one from a friend. Trust me, it'll make your life easier.
Alright, let's do the math! Drumroll, please... The hydrogen ion concentration is approximately 0.0794328 moles per liter. Voilà!
If you need any more calculations or have any more questions, feel free to ask!
To calculate the hydrogen ion concentration (also known as the H+ concentration or [H+]) from a pH value, you need to use the equation:
[H+] = 10^(-pH)
In this case, the given pH value is 1.10. Plugging it into the equation, we get:
[H+] = 10^(-1.10)
Using a scientific calculator, you can find the answer by typing "10", then raising it to the power of (-1.10) or (-1.1). The result is the hydrogen ion concentration in moles per liter.
Alternatively, you can use the logarithmic function on your calculator. Most calculators have a "log" or "log10" button. In this case, you would enter "1.10", press the "log" button, and then change the sign of the result to negative to get the hydrogen ion concentration.
I hope this helps! Let me know if you have any further questions.
To calculate the hydrogen ion concentration (H+) from a given pH value, you can use the equation:
[H+] = 10^(-pH)
In this case, to find the hydrogen ion concentration for a pH of 1.10, you would substitute the value into the equation:
[H+] = 10^(-1.10)
Now, if you want to use a calculator to evaluate this expression, you can follow these steps:
1. Turn on your calculator and make sure it is in the standard mode.
2. Enter the negative value of the pH, i.e., -1.10, using the appropriate key/button. Be cautious with the order of operations on your calculator, as some calculators require parentheses for negative exponents.
3. Press the exponentiation key/button ("^" or "x^y").
4. Enter the base of the exponentiation, which in this case is 10.
5. Press the equals "=" key/button to obtain the result.
The resulting value will give you the hydrogen ion concentration in moles per liter (mol/L) for the specified pH value.
For example, using the calculation above, you would find:
[H+] = 10^(-1.10) ≈ 0.07943 mol/L
Therefore, the hydrogen ion concentration for a pH of 1.10 is approximately 0.07943 mol/L.
