Action of sodium hydroxide on 0.1 bromothymol blue?
When sodium hydroxide reacts with 0.1 bromothymol blue, the solution turns blue initially due to the presence of bromothymol blue in its acidic form. As the sodium hydroxide neutralizes the acid, the solution changes color from blue to green and finally to yellow, indicating the increasing pH level. This color change is a result of the indicator's ability to change its molecular structure in response to changes in pH levels.
How is bromothymol blue made?
Bromothymol blue solution can be made by adding 20 milliliters of alcohol to 0.1 grams of bromothymol blue powder and 10 milliliters of 4 percent sodium hydroxide solution. Next, add one liter of of distilled water. If it looks green instead of blue, add some sodium hydroxide to it one drop at a time until it turns blue.
What is the action of sodium chloride on 0.1 bromothymol blue?
Sodium chloride will not have any significant impact on bromothymol blue since it is a neutral compound that does not affect the pH indicator properties of bromothymol 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 happens to Copper sulfate and sodium hydroxide when mixed together?
When copper sulfate and sodium hydroxide are mixed together, a double displacement reaction occurs. The copper ions from copper sulfate react with hydroxide ions from sodium hydroxide to form a blue precipitate of copper hydroxide. The resulting solution will contain sodium sulfate.

What is the action of potassium hydroxide on 0.1 bromothymol blue?
The color is dark blue.
What is the action of sodium chloride on 0.1 bromothymol blue?
Sodium chloride will not have any significant impact on bromothymol blue since it is a neutral compound that does not affect the pH indicator properties of bromothymol blue.
Colour of sodium hydroxide in bromothymol blue?
Bromothymol blue is a chemical indicator for weak acids and bases. The chemical is also used for observing photosynthetic activities or respiratory indicators (turns green then yellow as CO2 is added). Since dissolved O2 does not affect pH, the solution remains the same color it was when it was added (yellow for acidic, green for neutral, blue for alkaline).
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 happens to Copper sulfate and sodium hydroxide when mixed together?
When copper sulfate and sodium hydroxide are mixed together, a double displacement reaction occurs. The copper ions from copper sulfate react with hydroxide ions from sodium hydroxide to form a blue precipitate of copper hydroxide. The resulting solution will contain sodium sulfate.
What happens when you heat copper hydroxide and sodium nitrate?
When you heat copper hydroxide and sodium nitrate, a chemical reaction occurs where the copper hydroxide decomposes to form copper oxide and water, while the sodium nitrate decomposes to form sodium nitrite, oxygen gas, and nitrogen dioxide gas.
Copper sulphate add to sodium hydroxide result colour?
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
What happens to the indicator when hydrochloric acid is added to sodium hydroxide?
It turns from its original blue colour to red.
What happens when sodium hydroxide is added to copper oxide the colour of precipitate?
When sodium hydroxide is added to copper oxide, a blue precipitate of copper hydroxide is formed. The color of the precipitate is due to the formation of copper ions in solution.
What will be the effect of sodium hydroxide in blue litmus paper?
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
