What else can I help you with?
What indicator has no color at all?
phenolphthalien when added to an acidic solution has a colourless indicator. but shows pink colour for basic solution.
What word describes chemicals which change colour in acids and alkalis?
acid-base indicators for all pHs: universal indicator for pH testing in general: indicator
What color change does each indicator show to represent acids bases and neutral?
There are far too many indicators to give them all. Litmus is blue in alkali, red in acids and an in-between colour often called claret when neutral. Universal indicator is red in strong acids, blue in strong alkalis and different colours in between depending on the brand.
Why is starch indicator added after sodium thiosulphate?
Starch indicator is added after sodium thiosulphate in iodometric titrations to help visualize the endpoint of the reaction. Starch reacts with any excess iodine produced at the endpoint, forming a dark blue-black color, allowing for easier detection of when all the thiosulphate has reacted.
Why are mineral acids strong acids?
Mineral acids are strong acids because they completely dissociate in solution to release a high concentration of H+ ions. This dissociation happens easily due to the strong bond between hydrogen and the acidic components in mineral acids, leading to a high degree of ionization and resulting in a low pKa value.
What plant dye can be used to detect acids and alkalis?
The most common is Litmus. Litmus is extracted from various Lichens and is a good indicator of both acids and alkalis. Some naturally occurring substances indicate only acids or alkalis such as cochineal and curcumin. The common litmus paper is impregnated with the dye extract of the Lichen to act as an acidity or alkalinity indicator. All PH (acidity and alkilinity) measuring devices work based upon whether they accept or donate protons and as such are infact themselves acids or bases. For greater accuracy other dyes (other than the reactive element) are added to the PH detector which can be chemically engineered to give visible changes in colour at every step on the PH scale.
Why don't all acids turn indicators pink?
Not all acids turn indicators pink because the color change of an indicator depends on the pH of the acid. Different indicators have different color changes at different pH levels. Some indicators change color in acidic solutions, while others change in basic solutions.
All acids contain a replaceable?
All acids have hydrogen.
Are all acids disolved in water?
no, not all acids are dissolved in water!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What happens when you have two fractions that have the same denominator?
Nothing actually happens. You are now in a position where the fractions may be added or subtracted more easily but that is all.
What is an indicator blank?
During an experiment for chemistry, if an indicator will not work due to the lack of a reactant, the reactant can be added. You must then compensate for the added amount by creating a solution of the indicator and the the same amount of the reactant. The volume required in the blank titration must then be subtracted from the other results to obtain quality results. This is an indicator blank and how it is used.
Can hydroxyl groups be found on all amino acids?
No, hydroxyl groups are not found on all amino acids. Hydroxyl groups are typically found on amino acids such as serine and threonine, but are not present on all amino acids.
