Electronic pH probes and universal indicator solution/paper are the two main ways of finding numerical pHs.
To find find whether a substance simply has a pH greater or less than neutral pH 7, indicators like methyl orange and phenolphthalein can be used.
Google search images to find out what colours they go.
What else can I help you with?
Is hydrochloric acid a reagent?
Yes, hydrochloric acid (HCl) is commonly used as a reagent in various chemical reactions. It is often used as a strong acid to provide protons in a reaction, as a source of chloride ions, or for pH adjustment in laboratory settings.
What will be the pH of the solution formed by mixing 40ml of 0.1M HCl with 10ml of 0.45M NaOH?
To calculate the pH of the resulting solution when mixing HCl and NaOH, you need to determine the moles of each reactant. Use these values to find the limiting reagent and the excess reagent. Then, calculate the concentration of the excess reagent left in solution. Finally, use the concentrations of the excess reagent and water to determine the pH of the resulting solution.
What happens when you add methyl red reagent in excess amount?
If you add an excess amount of methyl red reagent, it can result in inaccurate pH measurements as the extra reagent may overpower the color change associated with the pH range being tested. This can lead to difficulty in interpreting the results and affect the reliability of the experiment.
Is cobalt chloride paper the same thing as pH paper?
No, cobalt chloride paper and pH paper are not the same. Cobalt chloride paper is used to test for the presence of water, while pH paper is used to test the acidity or alkalinity of a solution by measuring its pH level.
What can be used instead of phenolphthalein to measure pH?
Other pH indicators like bromothymol blue, methyl red, or universal indicator can be used as alternatives to phenolphthalein for measuring pH. Additionally, pH meters can provide a more accurate and continuous measurement of pH compared to indicators.
What is pH scale how it is used?
a pH scale is something used for measuring the strengths of acids and bases.
Is Buffer AL a reagent?
Yes, Buffer AL is a reagent commonly used in molecular biology and biochemistry experiments to maintain a stable pH during reactions.
Is hydrochloric acid a reagent?
Yes, hydrochloric acid (HCl) is commonly used as a reagent in various chemical reactions. It is often used as a strong acid to provide protons in a reaction, as a source of chloride ions, or for pH adjustment in laboratory settings.

Then, calculate the concentration of the excess reagent left in solution. Finally, use the concentrations of the excess reagent and water to determine the pH of the resulting solution.
How do you correct the pH of water?
By adding the necessary reagent, acidic or basic.
What element are you measuring the concentration of ions of when measuring the pH of a substance?
You are measuring the concentration of the cation of hydrogen. Hence the name 'power of Hydrogen' -> pH
How would you measure the pH of a colored substance?
with a PH measuring device
What happens when you add methyl red reagent in excess amount?
If you add an excess amount of methyl red reagent, it can result in inaccurate pH measurements as the extra reagent may overpower the color change associated with the pH range being tested. This can lead to difficulty in interpreting the results and affect the reliability of the experiment.
What are the principle of Esbach reagent?
The principle of Esbach reagent is based on the precipitation of proteins in urine using a reagent containing picric acid and citric acid. The amount of protein present in the urine is estimated by measuring the turbidity of the solution after adding the reagent and allowing it to settle. The result is expressed in grams per liter (g/L) of protein.
How do you test for acid rain?
by measuring its pH
Is it wfi used for inplace of lal reagent water?
The LAL reagent water can be sterile WFI or other water that show reaction with the specific LAL reagent with which it can be used, at the limit of the sensitivity of such reagent.
What reagent is used to detect protein in a solution?
biuret reagent
