Why might a scientist prefer to use Universal Indicator rather than a different indicator like litmus?
Litmus only differentiates between acidic and alkaline solutions. It does not give an accurate value of the degree of acidity of alkalinity. Universal Indicator can help measure the pH of the given solution as it does not just change from red to blue and vice versa, but in solution has a range of colours.
What else can I help you with?
An American scientist cannot understand an equation written by a Chinese Scientist true or false?
False. Chemistry and math are universal languages made up of symbols.
Why do scientist have different views?
to explain to the people what they found out and that person only.
What are the different attitude of good scientist?
scientific attitude
List 4 different types of scientist?
Biologist, Chemist, Physicist, Astronomer.
Was a scientist's lifestyle a cause or an effect of their brilliance in their field of interest?
Scientists have very different life styles, one from another. There is no single "scientific lifestyle." So how a given scientist lives might be either a cause or effect of that scientist's brilliance - presuming that scientist is brilliant, not all are - or it may have no relation at all to how brilliant a scientist is.
How are universal indicator and the pH scale linked?
Universal indicator is a solution composed of several different indicators, each of which changes color at different pH levels. The pH scale is a way to measure the acidity or alkalinity of a substance based on its concentration of hydrogen ions. Universal indicator's color change corresponds to different pH levels, making it a useful tool for determining the pH of a substance.
What colour does the universal indicator go with a lot of acid?
The universal indicator goes bright red. I thought it was dark red lol =D i joke! i knew it was bright red. that's what mr. bayes, my science teacher said. he used to be a scientist
How are universal indicators useful to scientist?
An Universal Indictator is more helpful because it shows the exact amount of acidity. Other indictators (example the red and blue litmus) just indicates whether or not the solution is acidic. The universal indicator gives you a specific color to which you can match a pH number therefore, telling you how acidic the soultion is.
Why do scientist look for signs off water on other planets?
Liquid water is an indicator that there is probably life present.
When and or why would a scientist use a pH indicator like phenol red instead of a definitive reading from a probe or litmus paper?
Maybe BIll DID IT!
A scientist has analyzed the chemicals that make of a sample of an unknown substance. Which chemicals would be the best indicator that the unknown substance is a plant?
cellulose and starch
A scientist working in a lab wants to determine the precise pH of a solution what tool should the scientist use to measure?
The scientist should use a pH meter to measure the precise pH of the solution. This device provides an accurate numerical value for the acidity or alkalinity of the solution.
What scientist defined the universal law of gravitation?
Sir Isaac Newton is the scientist who defined the universal law of gravitation.
A scientist working in the field wants to determine the approximate pH of swamp water using a simple and inexpensive technique.which tool should the scientist use to measure an approximate pH?
A pH indicator
What systems measurements is universal among scientist?
The metric system.
Who invented the universal joint?
The first universal joint was created by Londoner Robert Hooke, a scientist of the 17th century.
a scientist wants to test how much of an acid can be added to a solution before the ph of the solution changes to a certain point. Which PH indicator should the Scientist use?
Methyl yellow, which changes from yellow to red around a pH of 4.0
