If the pH value of a solution is 4.3 what is the concentration of hydrogen ions?
The solution to this problem is simple if you just work backwards. pH= -log10[H+] You already know what your pH is, so write your equation like this: 4.3= -log10[H+] An understanding of basic logarithm properties lets you know that you can rewrite the equation like this: 10-4.3= [H+] 5.0 *10-5 = [H+]
What is an equation that contains a variable?
It is an equation. It could be an algebraic equation, or a trigonometric equation, a differential equation or whatever, but it is still an equation.
What is an equation that relates quantities represented by variables?
Simply that, an "equation".Simply that, an "equation".Simply that, an "equation".Simply that, an "equation".
Do you answer an equation?
you don't answer an equation, you solve an equation
What is the Logarithmic formula that gives the pH of a substance?
The definitive answer is 'pH = -log(10) [H^(+)] In words, ' pH is the negative logarithm, to the base ten, of the hydrogen ion concentration. As an example If H^(+) is 0.002 Then pH = -log(10)[0.002] On the calculator using the 'log' button pH = -(-2.69897...) pH = 2.69897... pH = 2.70 NB This would be an acidic pH NNB pH is always quoted to 2 d.p. only. NNNB Do NOT use the 'ln' button on a calculator.
