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.

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.
Write the equation for determining pH?
pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter.
What is the base chemistry formula for determining the pH of a solution?
The base chemistry formula for determining the pH of a solution is pH -logH.
How is this different from determining if a value is a solution to an equation?
How is this different from determining if a value is a solution to an equation?
What is the pOH equation How can pOH be determined from pH?
pH + pOH =14
What is the method of determining an acid and a base?
The pH scale
What factor is most important in determining a protein's optimum pH level?
The most important factor in determining a protein's optimum pH level is its specific amino acid composition.
What has the author Ph W Zettler-Seidel written?
Ph. W. Zettler-Seidel has written: 'Nomograms for three ramjet performance equations (continuity equation, pressure equation, combustion equation)'
Why is pH important in science?
It is a precise measurement tool for determining how acidic (pH 0) to alkaline (pH 14) a solution of a chemical dissolved in water is.
Why is the exponent of a variable a determining factor in whether an equation is linear?
Because that is how a linear equation is defined!
Purpose for determining th pH of orange juice?
The purpose is to find out how acidic it is
How do you derive the isoelectric point equation from Henderson hasselbalch equation?
The isoelectric point (pI) is the pH at which a molecule has no net charge. To find pI from the Henderson-Hasselbalch equation, set the net charge of the molecule equal to zero and solve for pH. This equation is derived by considering the acidic and basic dissociation constants of the molecule to calculate the pH at which the net charge is zero.
Calculate the pH after mixing a buffer at pH 4 and 6?
The pH after mixing two buffers can be calculated using the Henderson-Hasselbalch equation, pH = pKa + log([A-]/[HA]), where [A-] is the concentration of conjugate base and [HA] is the concentration of the weak acid. Given pH of 4 and 6, the pKa can be determined and used in the equation to find the final pH value after mixing.
