What colour in sulfuric acid is phenolphthalein?
Phenolphthalein is colorless in sulfuric acid.
What colour is made by mixing bromothymol blue and sulphuric acid?
Mixing bromothymol blue and sulfuric acid would not result in a colour change, as sulfuric acid is a strong acid and bromothymol blue is a pH indicator that changes colour based on the acidity or alkalinity of a solution.
What is the action of sodium hydroxide on the colour of phenolphthalein?
Phenolphthalein is pink in basic solutions.Phenolphthalein is used as an indicator in volumetry - acid-base titration.
What colour does hydrochloric acid turn phenolphthalein?
It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
What happens when you mix water and sulphuric acid?
when we add water n sulphuric acid then dilute sulphuric acid is formed. But we have to mix concentrated acid to water not water to acid otherwise the container in which u r mixing may explode because this reaction is highly exothermic.
What colour does sulphuric acid turn litmus?
Sulphuric acid turns blue litmus paper red, indicating its acidic nature.
Why there is no colour change when phenolphthalein is added to the oxalic acid?
Oxalic acid is a weak acid and phenolphthalein is a pH indicator that changes color in the pH range of 8.2 to 10. Oxalic acid solutions typically have a pH below the range where phenolphthalein changes color, so there is no visible change when phenolphthalein is added to oxalic acid.
What colour would the red petal indicator be in a solution of sulphuric acid?
The red petal indicator would likely turn blue in a solution of sulphuric acid because sulphuric acid is a strong acid that would cause the indicator to change color.
What gas is made when mixing acid with magnesium?
when you mix sulphuric acid with magnesium you create a gas called hydrogen.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
How does phenolphthalein work?
Phenolphthalein is an indicator that undergoes a colour change from colourless to pink that begins at a pH of 8.0. So in the titration your performing the phenolphthalein will start to change colour at the point when the moles of acid equal the moles of base. Although this colour change occurs at a pH of 8.0 and not at a pH of 7.0 phenolphthalein is commonly used because of the distinctive colour change that occurs. Phenolphthalein is colourless in acids and pink/purple in base. It also turns orange in very strong acids.
How do you make 0.1 Molar of sulfuric acid?
9,8 g concentrated sulphuric acid to 1 L of water (attention to mixing !)
