HNO3 is a strong acid, which means it dissociates completely. This means you don't have to set up an equilibrium scenario; you can just go with the given molarity as also being the concentration of hydrogen ions [H+]. So, pH = -log(0.00884), which is about 2.05.

What is the pH of a naturall solution?
The pH of a neutral solution is 7 and the concentration of H+ or H3O+ in the solution would be 1.0 X 10-7.
Can the amount of a solution affect the pH of that solution?
pH is the acidity. low pH is more acid, while high pH is more basic.
Would the pH of a sodium hydroxide solution be above or below 7?
NaOH is a base so it will produce a pH above 7.
How does pH value of solution help to predict nature of solution?
An acidic solution has a pH under 7 and a basic solution has a pH over 7.
Which label would best describe a solution with a pH of 11?
a buffer is wrong, it is basic or alkaline, depending on the choices
What is the pH of a 0.01 M solution of the acid HNO3 in water?
- log(0.01 M HNO3) = 2 pH =====
What is the pH of 15 mL of 0.0045 M HNO3?
pH = - log10 [H+], where [H+] is the molar concentration of hydrogen ions. HNO3 is a strong acid and dissociates completely in water so a 5 M solution of HNO3 would have a concentration of hydrogen ions of 5M also. So, pH = -log10[5] = -0.699 which indicates an extremely strong acid.
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 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 )
What would be the pH of a neutral solution An acid solution A basic solution?
Neutral solution: pH =7Acidic solution: pH7.
How does a solution with a pH of 7 compare to a solution with a pH of 9?
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
If 0.630 grams of HNO3 molecular weight 63.0 are placed in a liter of distilled water at 25 degree Celsius what will be the pH of the solution?
2
What type of solution has a pH of 7.0?
A neutral solution would have a pH of 7.
If hno3 is added to water how does pH- change?
If nitric acid (HNO3) is added to water, it decreases the concentration of hydroxide ions in solution. This is because nitric acid semi-strongly dissociates in water, following this chemical reaction: HNO3(aq) + H2O(l)-->NO3-(aq) + H3O+(aq) The hydronium ions that are created in this reaction then react quickly with the hydroxide ions in the water, as shown in this chemical equation: H3O+(aq) +OH-(aq) --> 2H2O(l) This results in fewer hydroxide ions existing in solution.
What is the pH of 2M HNO3?
pH= -log [H+] = -log [1] = 0
Is NaNO3 acidic neutral or basic?
It would be expected to be near neutral, because it is produced by reacting nitric acid (HNO3) with sodium hydroxide (NaOH). It represents the salt product of a strong acid and a strong base, so its pH in solution will be very near 7.
How would you organize these in order pH concentration acid base and neutral?
pH = 0-7 acidic solution pH = 7 neutral solution pH = 7-14 basic solution
