What else can I help you with?
If you tested stomach acid with litmus what colour would it turn?
Stomach acid is acidic, so litmus paper would turn red when exposed to it.
What happens when sulphur dioxide dissolved in water is tested by blue litmus paper?
Burnt Magnesium ribbon ----> MgO (magnesium oxide)(basic in nature) When added to water, it forms its hydroxide MgO+H2O ----> Mg(OH)2 (which is a base) when added to litmus paper or litmus solution....it will give a light blue colour
Why is litmus paper useful?
Water provides H+/ OH- ions for the dry gas(to be tested with litmus) to show its acidic/alkaline nature.
What color of litmus is water?
Litmus paper is typically blue. If water is tested with blue litmus paper and it turns red, it indicates that the water is acidic. However, if there is no color change, the water is neutral.
What factors could be tested using litmus paper?
The acidity or alkalinity of a solution, pH indicator.
What colour will it be when a acidic is test with a blue litmus paper?
litmus paper turns blue litmus red when tested on an acid and red litmus blue when tested on a base
If you tested stomach acid with litmus what colour would it turn?
Stomach acid is acidic, so litmus paper would turn red when exposed to it.
What colour does vinegar go with litmus?
If the vinegar is strong enough to be below 4.5 pH the litmus paper will turn (or stay) red.
What happens when sulphur dioxide dissolved in water is tested by blue litmus paper?
Burnt Magnesium ribbon ----> MgO (magnesium oxide)(basic in nature) When added to water, it forms its hydroxide MgO+H2O ----> Mg(OH)2 (which is a base) when added to litmus paper or litmus solution....it will give a light blue colour
What is the colour of the pH of grape juice on litmus paper?
Grape juice typically has a pH ranging from 3 to 4, which is acidic. When tested with litmus paper, it would turn blue litmus paper red, indicating its acidic nature. Red litmus paper would remain red, as it does not change color in acidic solutions.
What experiment shows that sulphur forms an acidic oxide?
S+O2 gives rise to SO2. This is dissolved in water and tested with litmus paper.Red litmus turns blue which means it is acidic
How are acids and bases tested?
universal indicator or litmus paper
What color did the litmus paper turn to when you test tap water?
There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. -- Tap water will not cause any colour change when tested with litmus paper. Blue litmus paper remains blue, the same goes for red litmus paper. Although the above statement says that tap water is slightly basic, the pH is still close to neutral and will not be significant enough to cause a colour change for the litmus paper.
What if red litmus stays red?
If red litmus paper stays red when tested with a solution, it indicates that the solution is acidic or neutral, as red litmus is designed to remain red in acidic conditions (pH < 7). In contrast, if the solution were basic (pH > 7), the red litmus would turn blue. Therefore, a red litmus that stays red confirms the absence of basicity in the solution being tested.
Why is litmus paper useful?
Water provides H+/ OH- ions for the dry gas(to be tested with litmus) to show its acidic/alkaline nature.
How are Ph levels of a swimming pool tested?
Usually the ph is tested with a phenol red indicator but litmus paper can be used
What color of litmus is water?
Litmus paper is typically blue. If water is tested with blue litmus paper and it turns red, it indicates that the water is acidic. However, if there is no color change, the water is neutral.
