Yes it would
The Universal Indicator would go green which is pH 7.
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
nope
If universal indicator is added to water after a reaction with cesium, the solution would likely turn purple or dark blue. This is because cesium reacts vigorously with water to produce cesium hydroxide, which is a strong base. The formation of this alkaline solution raises the pH, causing the universal indicator to shift toward the color that corresponds to higher pH levels.
When bromine water is added to a solution containing a universal indicator, the color change depends on the pH of the solution. Bromine water is typically acidic, so if the solution is neutral or basic, the universal indicator may shift towards red or orange, indicating a lower pH. In a strongly acidic environment, it would turn red. Overall, the specific color change can vary based on the existing pH of the solution.
Yes, a soap solution would test as a base with universal indicator paper as soaps are typically alkaline in nature due to the presence of sodium or potassium hydroxide. This would cause the universal indicator paper to change color to indicate its basic pH.
Yes it would
The Universal Indicator would go green which is pH 7.
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
You could dip the universal indicator paper in each solution separately and observe the color change. Distilled water will not change the color significantly, indicating it is neutral. Sodium hydroxide solution will turn the paper blue or purple, indicating a strong alkaline solution. Ethanoic acid solution will turn the paper red, indicating an acidic solution.
nope
Universal indicator added to a toothpaste solution would likely turn a shade of blue or purple, indicating that the solution is basic due to the presence of substances like fluoride or calcium carbonate found in toothpaste.
The universal indicator would likely show a green color in an aqueous solution of sugar. This is because sugar is a neutral compound and does not significantly affect the pH of the solution, resulting in a green color indicating a neutral pH.
Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
To determine the pH of a solution using pH indicator paper, you would first dip the paper into the solution. The paper will change color based on the acidity or alkalinity of the solution. You can then compare the color of the paper to a pH color chart to determine the approximate pH level of the solution.
An alkaline of about a Ph of 10-14
