What is the concentration of the hydroxide ions of a solution whose pH is 4.0?
The concentration of hydroxide ions (OH-) in a solution with a pH of 4.0 is 1 x 10^-10 mol/L. This value can be calculated using the relationship between pH and pOH (pOH = 14 - pH), and then using the formula for the concentration of hydroxide ions in water at a given pOH.
How many times more acidic is a solution of pH 9 than a solution of pH 5?
Each number on the pH scale represents a 10-fold difference from the number before or after it, so that pH5 is 10x more acidic than pH6 which is 10x more acidic than pH7. Since the difference between 9 and 5 is 4, the acidity would be 4 tens multiplied together: 10 x 10 x 10 x 10 (or 104), BUT.... the question asks for the difference in acidity at pH9 compared to pH5. pH9 is weaker, so we use the inverse. pH9 is only 1/104 as acidic as pH5.
What is the freezing point of hydrochloric acid?
Depends on the concentration. 100% = 3C 93% = -32C 78% = -38C 65% = -64C See:http://www.cise.columbia.edu/clean/msds/sulfuricacid.pdf Remember that the temperatures are NEGATIVE!
What is the boiling point for maple sap?
The boiling point of maple sap is around 212°F (100°C). This is the point at which the water in the sap evaporates and the sugar concentration increases, leading to the production of maple syrup.
How many times more acidic or basic is a pH of 11?
Relative concentration [H+]1 / [H+]2 = 10-(pH1 -pH2) = 10-(7.0-11.0) = 104 == 10,000 times more basic than in pure water (pH=7.0)[Remember that dividing concentrations is substracting both log value of concentration]
What is the concentration of the hydroxide ions of a solution whose pH is 4.0?

What is the boiling point of concentrated aqueous solution of sodium chloride?
The boiling point of a concentrated aqueous solution of sodium chloride is higher than that of pure water. This is due to the presence of the solute, which raises the boiling point of the solution through a process called boiling point elevation. The exact boiling point will depend on the concentration of the sodium chloride in the solution.
At which temperature does a concentrated aqueous solution of sodium chloride begin to boil?
A concentrated aqueous solution of sodium chloride (table salt) will start to boil at a higher temperature than pure water, due to the colligative properties of the salt. The boiling point elevation for a 1 molal solution of sodium chloride is around 1.88°C.
What is negative 104 equals 8x?
It's a trivial linear equation in 'x'.You can find the solution like this:-104 = 8xDivide each side by 8:-13 = x
What percent of 200 percent is 104?
52%Solution:200 * (x/100%) = 104x/100% = 104 / 200x/100% = 0.52x = 0.52*100%x = 52%
What is 70 percent of 104?
Since the decimal form of 70% is 0.7, 70% of 104 would be 104(0.7). This equals 72.8.
What is 104 minus negative 13?
Whenever you minus a negative (number), you add. So it would be 104 - (-13), or 104 + 13, which is 117
What would 104 Fahrenheit be in Celsius?
It is: 5/9*(104-32) = 40 degrees Celsius
What angle equals to 104 degrease?
An angle that equals 104 degrees is simply referred to as a 104-degree angle. It does not have a specific name beyond its measurement. In terms of complementary or supplementary angles, the angle that complements it would be 76 degrees (90 - 104), and the supplementary angle would be -16 degrees (180 - 104), which indicates that 104 degrees is already greater than 90 degrees and cannot have a positive supplementary angle.
How many times more acidic is a solution of pH 9 than a solution of pH 5?

104 km how many m-?
If you have 104 KM it would turn out to be 109.4 M. This is taught in math.
How many times can go into 104?
To determine how many times a number can go into 104, you need to divide 104 by that number. For example, if you're asking how many times 4 can go into 104, you would calculate 104 ÷ 4, which equals 26. The answer will vary depending on the number you are considering.
