What else can I help you with?
What colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
When phenolphthalein is mixed with sodium chloride solution, no color changes will occur. Phenolphthalein is a pH indicator that changes color in response to pH levels, while sodium chloride (table salt) does not significantly affect the pH of a solution.
What effect does chlorine have on moist universal indicator?
Chlorine turns moist universal indicator paper red, then bleached. It has the same effect on blue litmus paper (red then bleached). this shows it is an acidic gas and so when reacts with sodium for example (an alkali metal) makes sodium chloride (salt).
What happens when sodium is added to water and universal indicator?
When sodium is added to water, it reacts vigorously, releasing hydrogen gas and forming sodium hydroxide. The solution will become alkaline due to the formation of sodium hydroxide. When universal indicator is added, it will change color to indicate a high pH level, typically turning purple or blue for strong alkaline solutions.
A hydroxide ion is indicated by?
As a chemical ion it is 'OH^-'. As in sodium hydroxide NaOH. A pH indicator will shown it as pH 8 to 12' depending on the ionic strength. A Universal Indicator will colour 'blue/violet/indigo'.
What colour of flame does sodium chloride produce when heated?
Sodium chloride does not produce a flame when heated. It simply melts into a liquid state and eventually vaporizes.
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 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
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 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 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 is the NaCl indicator?
Sodium chloride (NaCl) is not an indicator in analytical chemistry.
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.
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 will be the colour of bromothymol blue in a solution of sodium chloride in water?
Sodium Chloride solution has a pH of 7 & the Indicator color is green. Bromothymol blue indicator reflects a pH range of 3.5-9.5
What colour would sodium chloride produce in heat?
In a flame, sodium chloride produces a bright orange-yellow colour.
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.
