What is the pH of the solution after adding {eq}\displaystyle \rm 30.0 \ mL {/eq} of {eq}\displaystyle \rm 0.100 \ M \ NaOH {/eq} to {eq}\displaystyle \rm 20.0 \ mL {/eq} of {eq}\displaystyle \rm 0.200 \ M \ C_2H_2O_2H {/eq}....
What is the pH of battery acid? A solution has a hydrogen ion concentration of 1 x 10^6 M. What is the pH? If the pH of a solution is 4, what is the pOH? What is the pH of NaOH? You can find the pH of a substance by using ...
Question: What is the pH when 20.0 mL of 0.280 M acetic acid has been titrated with 40.0 mL of 0.120 M NaOH? Acetic Acid: Acetic acid defines a weak acid that is shown by a standard chemical formula {eq}\text{C}{{\text{H}}_{3}}\text{COOH} {/e...
Given: Mass of diprotic acid sample 0.117 g Concentration of NaOH 0.0500 M What are the moles of diprotic acid, H_2X present? What is the molar mass of the diprotic acid? The NaOH solution with a concentration of 0.188 M is used to titrate a diprotic acid of unkno...
Ka = [A-][H3O+] / [HA][H2O] This is used to calculate pKa, the logarithmic constant: PKA = – log10 Ka The larger the pKa value, the smaller the dissociation of the acid and the weaker the acid. Strong acids have a pKa of less than -2. ...

The Validity of Using the ASTM A923 Test Method C Corrosion Test for Weld Procedure Qualification of 25% Chrome Duplex Stainless Steels While Test Method A (electrolytic NaOH) etch can be used as a screening test, it is sometimes not permitted for this purpose by User specifications. This leav...
小明希望用稀硫酸和锌粒反应来制取氢气，但实验室提供的是溶质质量分数为98%的浓硫酸．试计算：（1）将10g浓硫酸配制成溶质质量分数为19.6%的稀硫酸，需要加水多少克？___（2）取上述配制好的溶质质量分数为19.6%的稀硫酸20g与足量锌粒充分反应，能制得氢气质量为多少克？___（3）充分反应后所得溶液中溶质...
As such,the logarithm function is the inverse function to exponentiation. By convention, “log” is taken to mean “log to base 10.” And remember, the “p” denotes anegativelogarithm. So, at the risk of jumping ahead, a solution with a molar concentration of 10-7protons has a pH of...
mL NaOH added will show an inflection point at the equivalence point. The size of the inflection point depends on the Ka of the acid. If the acid is too weak, this change is so small that it may not be seen. In part I of this experiment, acetic acid (a monoprotic acid) will ...
