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 universal indicator change to if sodium sodium by carbonate is added?
Universal indicator changes to green when sodium bicarbonate is added.
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 is sodium hydroxide in universal indicator?
Sodium hydroxide turns Universal Indicator solution dark purple, indicating it is a strong base with a high pH level.
What colour is sodium hydroxide when you add universal indicator?
When you add universal indicator to sodium hydroxide, it will typically turn purple or dark blue in color, indicating that the solution is strongly alkaline.
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 is sodium hydroxide when you add universal indicator?
When you add universal indicator to sodium hydroxide, it will typically turn purple or dark blue in color, indicating that the solution is strongly alkaline.
Which colour is produced when universal indicator is added to sodium bicarbonate?
Baking soda is sodium bicarbonate or sodium hydrogen carbonate It is alkaline and will therefore turn universal indicator purple or blue
What colour is sodium chloride in a universal indicator?
Sodium chloride is a neutral substance and will not exhibit a specific color in a universal indicator. Universal indicators change color based on the pH of a solution, not the presence of specific compounds like sodium chloride.
What colour will appear when hydrochloric acid react to sodium hydroxide with a few drop of universal indicator?
A green colour will appear due to the reaction of hydrochloric acid and sodium hydroxide. The universal indicator changes color in response to the pH level of the solution, and green indicates a neutral pH level.
What colour uvirsal indicator go if added to soudium chloride?
Sodium Chloride a.k.a. table salt or sea salt is neutral and so Universal Indicator will go Green with a Ph 7
Color of sodium carbonate in universal indicator?
Sodium carbonate in universal indicator will typically appear blue or purple in color. This is due to the alkaline nature of sodium carbonate, indicating a high pH level.
What is the specific name of universal indicator?
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.
What colour does universal indicator turn if you add vinegar?
Because oven cleaner contains Sodium Hydroxide (Na OH), a 'strong' alkali/base, to dissolve the grease, it would change Universal Indicator a deep blue/purple colour.
