Question: What Is The PH Of 10 8 M Naoh?

What is the pH of 0.01 m h2so4?

pH= -log(H+) Here H+ refers to the concentration of H+ ions or the Hydronium ions.

Here it can be clearly observed that 1 moles of sulphuric acid gives rise to 2 moles of H+ ions.

which is equal to 1.698.

Therefore pH of 0.01 moles of H2SO4 is 1.698 or 1.70..

What is the pH of 10 9 M HCl?

Since its concentration is very low, you need to account for H+ ions of water as well. Hence total amount of H+ ions present will be 10^-9 + 10^-7 =1.01*10^-7. Hence pH would be -log(1.01*10^-7) = 6.99567.

What is the pH of 10 8 M HCl solution?

about 6.8Video Explanation The concentration of HCl is given as 10−8 M. pH is calculated based on the protons of the acid and the water. 10−8 M is a very low concentration and hence the protons from water are also considered. This gives the value of the pH of about 6.8 which is very close to 7.

What is the pH of a 0.0001 M solution of HCl?

around 3Thus, the pH of HCl = pH of 0.0001 M of HCl. The pH value of HCl is around 3. Thus the pOH value of HCl will be 14 – 3 = 11. From this we can conclude that the pOH of 0.0001 M of HCl is 11.

What is the pH of 0.02 m NaOH?

12.30pH of 0.02M of NaOH is 12.30.

What is the pH of 10 10 NaOH?

The pH of this solution would lie somewhere between 7 and 8. At such very low concentrations, pH or pOH cannot be determined by simply relying on the concentration of the alkali alone.

What is the pH of 0.01 m NaOH?

For example, the pOH at a 0.01 M solution of sodium hydroxide is 2, the pH of the same solution must be 14-2 = 12.

What is the pH of 0.5 m NaOH?

OH- conc. of NaOH is 0.5 , from this you can calculate pOH. Now you apply pOH+pH =14 (At 25 degree centigrade) to calculate pH of 0.5 M NaOH. So, pOH=-log[OH-] =- log(0.5) =0.3010 Hence, pH=14 – pH =13.69 .

What is the pH of 0.45 m of h2so4?

What is the pH of distilled water?

7.0Distilled Water is Acidic Normal distilled water has a pH of less than 7.0 and acidic because it dissolves carbon dioxide from the air. But, the healthiest state for the body is slightly alkaline, something that alkaline water ionizers encourage through water output at the pH 9.5 level.

What is the pH of 10 7 M HCl?

6.95So we see concentrration of water as 10^-7(H+ concenrration) . And form a quadratic equation . H+ concentration = concentration of HCL + CONCENTRARIOB OF WATER. The PH of a dilute solution of HCl is 6.95.

What is the pH of a 1.5×10 8 M solution of HCl?

PH = 7.00 D.

Is NaOH an acid or base?

NaOH, or sodium hydroxide, is a compound. A compound is classified as either an acid, base, or salt. All bases contain OH- (hydroxide) ions, while all acids contain H+ (hydrogen) ions. A salt is a compound that is formed when a base and an acid are combined because they neutralize each other.

What is the pH of a 10 4 m NaOH solution?

10.0 (2) What is the pH of a 0.0001 M NaOH solution? SOLUTION: Strong base so, pOH = -log[NaOH] = -log(0.0004)=-log(1×10-4)=4.0 pH = 14.0-pOH = 14.0 – 4.0 = 10.0 (makes sense since we expect basic solution).

What is the pH value of 1 m NaOH?

For 0.1M NaOH], pOH=-log(0.1)=1, which means the pH=13, (remember pH+pOH=14), but 13 has two sig. figures, so you must use the convention in figure 16.2. 2, and the answers are pH=1.0 for 1MHCL, and pH=13.0 for 1M NaOH.

How do you make a 10m solution of NaOH?

Add 40 g NaOH to a suitable container. Add distilled water to make solution up to 100ml.

How do I calculate pH?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].

What is the pH of 10 10 HCl?

pH of Solution with Very Dilute Acid In this problem, a 10 – 10 M solution of HCl contributes 10 – 10 M [H +]. The ionization of water contributes 10 – 7 M [H +]. The effective [H +] of this solution is 10 – 7 M and the pH=7.
