Question

Measurements show that the pH of a particular lake is 4.0. What is the hydrogen ion concentration of the lake?
a. 4.0 M
b. 10−10 M
c. 10−4 M
d. 104 M

Accepted Answer

Hello everyone. And for today's problem we have that the hygiene in concentration of a particular lake is 10 to the negative five moller the ph of the lake should be. And so were given several ph numbers and were asked to identify what it would be. So for this problem we can go straight ahead and use the ph formula to calculate it. The P. H. Is equal to a negative log of the hydrogen ion concentration of the lake. In this case, we're told that the hydrogen ion concentration is 10 to the negative five moller so we can go ahead and plug that into directly into our formula. When we make this calculation, we have that the ph of the lake is going to be negative negative five. Because the logarithmic calculation of log of 10 to a negative five is negative five. If we distribute the negative sign, we're going to have that. The final answer for problem is five, which in our answer choices is answer choice. Thank you very much for sticking around until the end of this problem. I really hope it helped you and I hope to see you on the next one.
