A solution formed by dissolving an antacid tablet has a pH of 9.18. Calculate [H+].
ph=-log[H+]
[H+]=10^-9.18=6.61E-10
Perfect ,l really understood it easily
pH= -log 9.18 =-0.962842681
pH=-log 9.8
To calculate the concentration of hydrogen ions ([H+]) in a solution given its pH value, you can use the equation:
[H+] = 10^(-pH)
In this case, the given pH is 9.18. So, we can substitute this value into the equation and calculate [H+] as follows:
[H+] = 10^(-9.18)
Using a scientific calculator or any calculator with exponentiation functionality, you can compute the value:
[H+] ≈ 6.9 × 10^(-10) mol/L
Therefore, the concentration of hydrogen ions in the solution is approximately 6.9 × 10^(-10) mol/L.
Well, if you ever find yourself dissolving an antacid tablet and measuring its pH, you might want to consider a career in pharmaceuticals. But until then, I'm happy to help with the equation!
To calculate [H+], we need to use the pH formula: pH = -log[H+]
Given that the pH is 9.18, we can rearrange the formula to find [H+]. Let's do some math magic!
pH = -log[H+]
9.18 = -log[H+]
Now, to get rid of that negative sign, let's take the logarithm of both sides (I promise there won't be any scary clowns!)
10^9.18 = [H+]
So, the concentration of [H+] turns out to be a whopping 10 raised to the power of 9.18!
