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 blood?
The pH scale, ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40.
What is the pH of 0.005 m NaOH?
2.52(b) 0.005 M NaOH. (c) 0.002 M HBr. (d) 0.002 M KOH. Hence, the pH of the solution is 2.52.
How do you calculate the pH of NaOH?
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.
What is 0.5 N NaOH?
A 0.5 M NaOH is then 20 g NaOH/L. So dissolve 20 g NaOH in 500 ml water let it cool down to room temperature and fill it up to one liter. For accurate results you can use an analytical balance and a volumetric flask.

What is the pH of 0.02 m NaOH?
12.30pH of 0.02M of NaOH is 12.30.
How do you calculate the acidity of NaOH?
Thus, 0.00126 moles of NaOH (Step 2) would interact with 0.00063 moles of tartaric acid. Divide the number of moles of the acid (Step 4) by the aliquot volume and then multiply by 100 to calculate the acid amount in 100 ml of the solution. In our example, amount (C4H6O6)=0.00063 moles x 100 ml/15 ml=0.0042 moles.
What is N 10 NaOH?
N means normality, one normal of NaOH solution contains 23+16+1=40 grams( gram molar mass) of NaOH therefore, N/10 equals 40/10=4 grams. So, add four grams of sodium hydroxide to one litre of water then the N/10 NaOH solution is prepared.
How can we prepare 0.1 N NaOH in 100 ml?
To make 0.1N NaOH solution = dissolve 40 grams of NaOH in 1L of water. For 100 ml of water = (4/1000) × 100 = 0.4 g of NaOH. Thus, the amount of NaOH required to prepare 100ml of 0.1N NaOH solution is 0.4 g of NaOH.
What is the pH of 0.1 m NaOH?
13NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. Therefore pH of 0.1 M NAOH solution is 13.
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.
How is pH value calculated?
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+].
