What is the pH of a solution with H plus equals 9.40 x 10-4?
-log(9.40 X 10^-4) = 3 pH
How do the numbers in the pH scale relate to exponents or powers of ten?
The pH scale measures the acidity or alkalinity of a solution on a logarithmic scale, where each whole number change represents a tenfold difference in hydrogen ion concentration. For example, a solution with a pH of 3 has ten times more hydrogen ions than a solution with a pH of 4, which corresponds to a concentration of (10^{-3}) moles per liter compared to (10^{-4}) moles per liter. Thus, pH values are inversely related to the concentration of hydrogen ions, expressed in powers of ten.
What is the pH of an aqueous solution with a H plus concentration of 1 X 10-3 M?
3: The negative of the logarithm (base 10) of the concentration. The logarithm of 1 is 0 and the logarithm of 10-3 is -3; the logarithm of their product is the sum of their individual logarithms, -3 in this instance, and the negative of -3 is +3.
What is the pH of a solution with a H plus equals 1.4 x 10-3 M?
-Log(1.4x10-3)= 2.85 The Log to be used here is the decimal one, not the neperian one.
What is the pH when the hydrogen ion concentration is 2.0 x 10-3 M?
- log(2.0 X 10 -3 M) = 2.7 pH ======
What is the pH of a solution with H 2.3 10-3?
2.64
What is the pH of a 1.6 10-3 M HNO3 solution?
pH = -log[H+] pH = -log[1.6 × 10-3] pH = 2.8
What is the pH of a solution that has a concentration of hydrochloric acid equal to 0.001 M?
Remembwer pH is = the negative logarithm to base ten, of the hydrogen ion concentration . So with a concentration of 0.001 M The hydrogen ion concentration is 0.001 = 10^(-3) ph = -log(10)[H^+] pH = -log(10)10^-3 pH = -(-3) log(10)10 ( Remember log(10)10 = 1 ) pH = -(-3)(1) = --3 = 3 pH = 3
If pH is 3 what is the concentration of Hydrogen?
The concentration of hydrogen ions in a solution with a pH of 3 is 1 x 10^-3 mol/L.
What is the pH of a solution with H plus 2.3 10 -3?
5.0 x 10-3 pH = - log [H3O+] [H3O+] = 1 x 10^-pH pH = 2.3 [H3O+] = 1 x 10^(-2.3) = 5 x 10^(-3) M
What is the pH of resultant solution if solution with pH 3 and pH 8 are mixed?
To find the pH of the resultant solution, you can use the formula: pH = -log[H+]. Calculate the [H+] concentration for each solution using the pH values (pH 3 = 1.0 x 10^-3 M and pH 8 = 1.0 x 10^-8 M) and add them together. Then, convert the total [H+] concentration back to pH using the formula mentioned earlier.
What solution has a greater concentration of hydrogen ions a solution with a pH of 3 of a pH of 5 Explain?
1/103 = 0.001 M ========( pH 3 ) 1/105 = 0.00001 M ============( pH 5 ) As you see, a pH of 3 has a 100 times concentration of 5 pH ( 10 * 10 devalued ) This is the scale; logarithmic.
How many times more hydroxide ions are there in a solution with a pH of a 9 than in a solution with a pH of 3?
The pH scale is logarithmic, so each unit corresponds to a 10-fold difference in hydrogen ion concentration. Therefore, a solution with a pH of 9 has 1,000,000 (10^6) times more hydroxide ions than a solution with a pH of 3.
What pH of 4 is times more acidic as a pH of 7?
As the pH decreases, the solution becomes 10 times more acidic for each point. A solution of pH 4 is 10 times more acidic than a solution of pH 5. A solution of pH 3 is 10 times more acidic than a solution of pH 4. 10 x 10 = 100 A solution of pH 3 is 100 times more acidic than a solution of pH 5.
How many more hydroxide ions are there in a solution with a pH of 9 than in a solution with a pH of 3?
The concentration of hydroxide ion is realted to pH by the pKw (10-14) At pH 9 the concentration of OH- is 10-5, at pH 3, 10-11. The ratio is 106 so there are a million times as many OH- in pH 9.
