What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
What colour does a universal indicator change to when it is mixed with ethanol?
A universal indicator changes to a greenish-blue color when mixed with ethanol.
What colour should weak acid be in a universal indicator?
A weak acid would typically be a shade of orange or red in universal indicator, indicating a pH of around 4-6.
What colour should sulfuric acid be after universal indicator is added?
Sulfuric acid is a strong acid and will turn universal indicator red when added, indicating a pH of around 0-1.
What colour should sodium bicarbonate be in universal indicator?
Sodium bicarbonate would turn blue or purple in universal indicator solution, indicating a basic pH level, around pH 9-10.
What colour should face wash go when universal indicator is added?
green

What colour should sodium bicarbonate be in universal indicator?
Sodium bicarbonate would turn blue or purple in universal indicator solution, indicating a basic pH level, around pH 9-10.
What colour should sodium be in universal indicator?
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
What colour should the universal indicator go if its base?
Dark green (slightly alkaine), Blue (moderately alkaine), purple (strongly alkaline).
What colour does acid rain turn universal indicator?
Acid rain turns universal indicator red. This is because universal indicator is a mixture of dyes that change color in response to different pH levels, with red indicating acidity.
What pH indicator should the scientists use?
Scientists should consider using universal pH indicator because it can provide a wide range of colors to indicate different pH levels.
Why is thymol blue used as the indicator for titration of acetic acid and naoh?
Thymol blue changes color in the pH range of 8.0 to 9.6, making it suitable for titrations involving acetic acid (pKa ~ 4.75) and sodium hydroxide. At the equivalence point of the titration, the pH is around 8.5, which falls within the indicator's color change range, allowing for a sharp color transition at the endpoint.
Which hair colour is sexier?
There is no universal "sexy" hair colour. Hair colour is a personal preference. Your hair colour should be a similar shade to your eyebrows and should compliment your eyes. Ask a professional hair stylist what colour suits you.
