Phenolphthalein turns colorless in acid solutions and very strong base solutions.
pH level Check the pH level of the solution with a piece of litmus paper.
because distilled water does not conduct electricity and tap water does and also to see weather methanol conducts electricity.
dip the ph paper (0-14) in to water than dip in to the toluene .observe the colour change of ph paper after dipping in to the water .if any change it shows ph weather it is acidic or alkaline.if it remains same as water ph shown on paper.it is neutral . my question is that weather i am doing right or wrong. give me suggestion.
it is chemical and and u can weather it
that depends on weather or not you want the water in the end. if not just boil it, if so than you would need to use distillation.
I would like an all-encompassing solution for my news, weather, stocks and sports, is my earthlink a viable solution?
yes
Not really, the total energy from testing is tiny (very tiny) compared with atmospheric energy.
This is not an answerable question. The testing changes depending on what vehicle you are testing on, what the weather is like and other consideration's.
Models for predicting weather rely heavily on using past meteorological data for development and testing.
Replace weather seal.
You can't really generalize a phase of the AO to the weather in Texas, and the neutral "phase" is especially uninteresting. Besides, the AO oscillates frequently enough that it's never neutral for too long.
pls help me and find the solution to the question above pls help me and find the solution to the question above weather and wind force in the light of seamanship and navigation
pH level Check the pH level of the solution with a piece of litmus paper.
Clear solution or in a very extreme cold weather in air.
You can predict the weather using special technology and testing where the clouds are at what time of day and when they will move to hide the sun (to create a dull day) or when the clouds do not block the sun (to create a sunny day).
The exact number of animals that die each year from drug testing is difficult to determine as it varies depending on the scope and type of testing being conducted. However, it is estimated that millions of animals are used and may die annually in research testing worldwide.
