What does the pH scale express?
Pure Hydrogen
What is the pH of 10.0L of 0.0020 M HCL?
0.002M HCl means 0.002 moles HCl in 1L solution. Therefore 0.02 moles HCl in 10L solution. pH = 2-log2 = 2-0.3010 = 1.6990
What is the pH of acid rain?
pH is the scale used by scientists to express the aidity of acid rain.
What If enough water is added to 5 g of HCl to make 1 liter of solution what is the pH?
Find moles HCl. 5 g HCl (1 mole HCl/36.450 grams) = 0.1372 moles HCl Now, Molarity = moles of solute/Liters of solution Molarity = 0.1372 moles HCl/1 liter = 0.1372 M HCl Then. -log(0.1372 M HCl) = 0.9 pH ( you might call it 1, but pH can be off the scale ) -----------
What is the pH of a solution that contains 1.32 grams of nitric acid dissolved in 750 milliters of water?
Two steps. Find molarity of nitric acid and need moles HNO3.Then find pH. 1.32 grams HNO3 (1 mole HNO3/63.018 grams) = 0.020946 moles nitric acid ------------------------------------- Molarity = moles of solute/Liters of solution ( 750 milliliters = 0.750 Liters ) Molarity = 0.020946 moles HNO3/0.750 Liters = 0.027928 M HNO3 ----------------------------------finally, - log(0.027928 M HNO3) = 1.55 pH ==========( could call it 1.6 pH )
When an strong acid and weak base meet What is the pH?
The pH that results when a strong acid and strong base are mixed will depend on the moles of acid and moles of base present. One cannot predict the pH without knowing, or being able to calculate, the moles of each.
A solution has 0.000001 moles of hydroxide ions per liter - what is the pH of the solution?
pH is 8
What is it when The number of moles of hydrogen ions equals the number of moles of hydroxide ions?
A neutral solution of about 7 pH.
What would be too low of a pH?
Typically, the pH scale runs from 0-14, but there is technically no limit to the pH scale. A pH of -25 (for instance) would mean the H3O+ concentration is somewhere in the neighborhood of 1025 (moles/L). Likewise, a pH of 25 would indicate an H3O+ concentration of about 10-25 (moles/L).
Does molality express concentration?
yes in moles per kilogram
What does the pH scale express?
Pure Hydrogen
The equivalence point reached when the pH reaches it maximum value?
No. The equivalence point is reached when the moles of titrant equals the moles of analyte.
What can the coefficients in a balanced chemical equation always express the ratio of?
Moles of one substance compared to moles of the second substance. Ex. moles of reactant A compared to moles pf product F
What is the pH of acid rain?
pH is the scale used by scientists to express the aidity of acid rain.
What is the pH of 10.0L of 0.0020 M HCL?
0.002M HCl means 0.002 moles HCl in 1L solution. Therefore 0.02 moles HCl in 10L solution. pH = 2-log2 = 2-0.3010 = 1.6990
How are molarity and molality similar?
Both express moles of solute in the numerator.
Do moles express concentration?
Yes, the mol is the SI unit of concentration.
