How do you calculation pH from ka?
pH = pKa + log([A-]/[HA]) pH = pKa+log([conjugate base]/[undissociated acid]) pKa is also a measure of the strength of an acid. A low pKa is a strong acid, a higher pKa is a weak acid.
What is the pH of a solution with a H3O of 7.9x10-11 M?
The pH of a solution with a H3O+ concentration of 7.9x10-11 M is approximately 10.1. This is because pH is calculated as -log[H3O+], so -log(7.9x10-11) ≈ 10.1.
What is the pH of a solution whose hydronium ion concentration is 5.03 and nbsp and acute and nbsp10-1 M?
The pH of a solution can be calculated using the formula pH = -log[H+]. Given that the hydronium ion concentration is 10^-1 M, the pH of the solution is pH = -log(10^-1) = 1. So, the pH of the solution is 1.
How much does a log for the fire weigh?
The weight of a log for a fire can vary depending on the type of wood and its size. On average, a medium-sized log can weigh around 10-20 pounds.
What is the pH of a solution in which the hydronium ion concentration is 0.0002 M?
pH = -log[H3O+] = -log(2.6*10-9) = -(-8.58) = 8.6

How does one find the integral of secant cubed of x dx?
Find I = ∫ sec³ x dx. The answer is I = ½ [ log(sec x + tan x) + sec x tan x ]. * Here is how we may find it: Letting s = sec x, and t = tan x, we have, s² = 1 + t², dt = s² dx = (1 + t²) dx, and ds = st dx. Then, we obtain, dI = s³ dx = s dt. * Now, d(st) = s dt + t ds = dI + t ds = dI + st² dx = dI + s(s² - 1)dx = dI + s³ dx - s dx = 2dI - s dx; whence, 2dI = s dx + d(st). * Also, we have, s = (s² + st) / (s + t), whence s dx = (s² + st) dx / (s + t) = (dt + ds) / (s + t) = d(s + t) / (s + t) = d log(s + t). This gives us, 2dI = d log(s + t) + d(st). Integrating, we easily obtain, I = ½ [ log(s + t) + st ], which is the answer we sought. * Checking that we have arrived at the correct answer, we differentiate back: d(st) / dx = (st)'= st' + ts' = s³ + st² = 2s³ - s. d log(s + t) / dx = log'(s + t) = (s + t)' / (s + t) = (st + s²) / (s + t) = s. Thus, 2I' = [ st + log(s + t) ]' = 2s³; and I' = ½ [ st + log(s + t) ]' = s³, confirming that our answer is correct.
What s the G of x if it equals log 2 x plus 2?
G(x) = log(2x) + 2, obviously!
