pH is the negative logarithm to the base ten of the hydrogen ion concentration.
Mathematically.
pH = - log(10)[H^+]
Since H ^+ is 2.45 x 10^(-5)
Substitute in
pH = -log(10)[2.45 x 10^(-5)]
On your calculator using 'log' button.
pH = -(-4.610833916)
Double negative
Hence
pH = 4.61 ( pH is always quoted to 2 d.p.).
The inverse process is
[H^+] = 10^(-pH)
What else can I help you with?
If a solution has a hydrogen ion concentration of 10-5M what is its pH?
The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5
What corresponding hydronium ion concentration would a pH 5 solution have?
[H3O+] = 10-pH = 10-(5.0) = 1.0*10-5 mol/LpH= the negative log of the hydrogen ion concentration, pH=5 would be a concentration of 10(-5) or 0.00001 moles per liter
How many times pH of 4 is more than pH 5?
The H+ concentration is 10 times higher at pH=4 than at pH=5, according to the formula definition:[H+] = 10-pHSo 10-4 = 10 * 10-5 that's why, you see!
What is the pH of a solution whose h3o is 1 x 10 -5 m?
The pH of a solution with an H3O+ concentration of 1 x 10^-5 M is 5. This is because pH is defined as -log[H3O+], so by taking the negative logarithm of 1 x 10^-5, the pH is 5.
How many times stronger is a pH of 5 than a pH of 8?
A pH of 5 is 1,000 times stronger (10^3) than a pH of 8. Each unit change in pH represents a 10-fold difference in hydrogen ion concentration, so the difference between pH 5 and 8 is 10^3.
If a solution has a hydrogen ion concentration of 10-5M what is its pH?
The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5
How do you divide 5 into 245?
I would divide 5 into 245 by doubling 245 and then dividing by 10: 245 x 2 = 490 490 ÷ 10 = 49 ⇒ 5 divided into 245 is 49. To divide 5 into 245, the normal method is: Work from left to right: 5 doesn't go into 2 5 goes into 24 4 times, remainder 4 5 goes into 45 9 times. so 5 divided into 245 is 49. This would normally be written something like: ......... 49 .....------ . 5 | 245 ...... 20 ...... --- ........ 45 ........ 45 ........ --- .......... 0
What corresponding hydronium ion concentration would a pH 5 solution have?
[H3O+] = 10-pH = 10-(5.0) = 1.0*10-5 mol/LpH= the negative log of the hydrogen ion concentration, pH=5 would be a concentration of 10(-5) or 0.00001 moles per liter
How many times pH of 4 is more than pH 5?

What is the pH if OH is 1x10 5 M?
- log(1 X 10^-5 M) = 5 14 - 5 = 9 pH ----------
What is the total value of 245 in 10-dollar bills?
To find the total value of 245 in 10-dollar bills, you divide 245 by 10. This gives you 24.5, meaning you could have 24 full 10-dollar bills, which totals $240, with an additional $5 remaining. Therefore, the total value of 245 in 10-dollar bills is $240 in bills, plus $5 in smaller denominations.
What is the LCM of 49 and 245?
245 1*245 = 245 49*5 =245
What is the pH if the concentration of H plus ions is 4.5 times 10 to the -8?
if the pH is 4.7, the H+ concentration is 2 x 10-5
What is the pH of a solution whose h3o is 1 x 10 -5 m?
The pH of a solution with an H3O+ concentration of 1 x 10^-5 M is 5. This is because pH is defined as -log[H3O+], so by taking the negative logarithm of 1 x 10^-5, the pH is 5.
What the the factors of 5?
elevation,wind,latitude, precipitation and temperature
How many times stronger is a pH of 5 than a pH of 8?
A pH of 5 is 1,000 times stronger (10^3) than a pH of 8. Each unit change in pH represents a 10-fold difference in hydrogen ion concentration, so the difference between pH 5 and 8 is 10^3.
What is the prime factorization of 245 using exponents?
The prime factorization of 245 is 5 x 7 x 7, or 5 x 7^2. This can be written in exponential form as 5 x 7^2, where 5 is raised to the power of 1 and 7 is raised to the power of 2. This means that 245 can be expressed as the product of its prime factors, with 5 occurring once and 7 occurring twice.
