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 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 is one way that the pH of an acid can be determined?
By using red and blue litmus paper.Answer:There are many methods:Indicator papers - some as primitive as litmus and others supporting a graded change in colour over a pH rangeTitrations using indicator solutionspH metersAll of these will give you a pH value (usually 0-14) which indicates the negative of th log of the H+ ion (moles/liter) concentration in the solution.
SI unit of enzyme?
An enzyme unit is th accepted SI unit. One enzyme unit catalyses the breakdown of 1micromole of substrate at 25 degrees celsius at optimum pH, temperature, enzyme concentration etc.

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.
