What is the pH of 0.5 m NaOH?

What is the pH of 1 M HCl?
Hi, as professor Thomas Proft said pH= -log[H3O+], thus HCl 1M has a pH=-1, however pH has been defined between 0 and 14, according to the water constant (pK=14).
What is 0.1 N NaOH?
So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter. For a 0.1 N solution (used for wine analysis) 4.00 g of NaOH per liter is needed.
What is the pH of a .10 M solution of HCl?
The calculated pH of 10M of HCl is, -1.
How do you find the pH of 0.1 m NaOH?
Calculate the pH of a 0.1 M NaOH solution. Alternatively we can calculate pOH = – log [OH-]= – log [10-1] = 1 and remembering that pH + pOH = 14 we get pH = 14 – 1 = 13.
How does NaOH increase pH?
pH. … The hydroxide ions from dissolved sodium hydroxide perturb this balance; as the additional hydroxides accept protons from hydronium ions, they decrease the hydrogen ion concentration, thereby increasing the pH. Adding more sodium hydroxide will increase the pH of the water or make it more basic.
Is NaOH a base or acid?
NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion.

What is pH of HCl in stomach?
HCl is an important component in gastric juice. It is a strong acid produced by the parietal cells in the corpus generating a gastric pH of 2-3. Activation of pepsin and absorption of nutrients relies on an acidic pH in the stomach.
What is the pH of 0.02 m NaOH?
12.30pH of 0.02M of NaOH is 12.30.
What is the pH of milk?
about 6.7 to 6.9Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.

What is 0.5 N NaOH?
One mole of NaOH in one Liter of pure water = 1 N. Since you want 0.5, use 1/2 mole (20.0 grams) of NaOH. … M means Gram Molecular Weight, so 0.5 M means half the gram molecular weight of the chemical. In the case of NaOH the mole. wt. is Na=23, O = 16, H =1, so NaOH = 40.
How do you calculate the pH of sodium hydroxide?
To calculate pH, apply the formula pOH = -log[OH-]. Work out -log[0.1] = 1. Next, apply the formula pH + pOH = 14. To isolate the pH, work out 14 – 1 = 13.
