How can th pH of a solution be calculated if the pOH is known?
We can subtract pOH from 14, using the formula pH + pOH = 14. This is only true at 14 degrees Celsius.
How would you determine soil pH?
The pH of soil can be easily measured using a pH paper, the method is as follows:Things needed:Soil SampleWaterpH paperTest tubeTongsProcedure:First make a concentrated solution of soil in water.Pour it into a test tube.Using tongs, introduce pH paper in Test tube.Note the color change and match it with your pH chart.
Methyl orange solution 0.1 percent?
1. Weigh 0,1 g of metyl orange on an analytical balance to the nearest o,oo1 g. 2. Dissolve o,1 g of methyl orange in approx. 80 mL of distilled water in a volumetric flask of 100 mL. 3. Maintain the flask 30 min in a thermostat at 20 0C. 4. Add water up to the mark. 5. Transfer the solurtion in a clean and dry bottle. 6. Join an adequate label on th bottle (name of the solution, concentration, date, operator).
What is the acidity level in th mouth?
The acidity level in the mouth, known as pH, typically ranges from 6.5 to 7.5. Saliva helps to maintain this pH balance, which is important for dental health as lower pH levels can lead to tooth decay and erosion. Factors such as diet, oral hygiene, and overall health can influence the acidity level in the mouth.
What is th ph of astringent?
The astringency of a substance is not directly related to pH. Tannins and salicylic acid are both astringents, but the pKa values of these compounds are different. The pH would also depend on the concentration of the astringent agent. Many astringents are acidic, but some are basic. For example, aluminum acetate is a basic astringent.

What colour is methyl red in alkali?
When you add methyl red to a solution it will indicate it's pH. When the pH is under 4.4 the solution will appear red in color (or maybe pink). When the solution is above pH 6.2 it will appear yellow in color. Any where in between will appear orange. So if you add base to a red/pink or orange solution it will turn yellow as the solution becomes more basic. But I honestly do not know th actual chemical reaction that causes the indictor's color change.
How can th pH of a solution be calculated if the pOH is known?
We can subtract pOH from 14, using the formula pH + pOH = 14. This is only true at 14 degrees Celsius.
What is th pH value of carborane acid?

Factory smoke has led to acid rain that lowered the pFactory smoke has led to acid rain that lowered the pH of a lake to 5.0. What is the H plus concentration in the lakeH of a lake to 5.0. What is th?
The H+ concentration in a solution with a pH of 5.0 is 1 x 10^-5 mol/L. This is because the pH scale is logarithmic and each unit change represents a 10-fold change in H+ concentration. So, in a solution with a pH of 5.0, the H+ concentration is 1 x 10^-5 mol/L.
