Acid music studio 6.0 activation code?
You have to buy the activation code because each code is different. It will be available on their website.

Do Filthy Frank and Eminem know each other?
I highly doubt it, but hopefully it will happen. Pink guy and Eminem would be a nice rap duo.

What happen between Nick Jonas and Selena Gomez?
They dated for about a year, but less then a year. They could NEVER spend any time with each other. They were spotted together ONCE! They still remin godd friends.
When phenolphthalein is added to a basic solution what happens?
That really depends on the strength of the acid, the antacid, and how much of each are present in a mixture. Phenolphthalein is a pink in the presence of higher strength bases (pH > 8.2), orange in the presence of very strong acids (pH < 0), and colorless between pH 0 and 8.2, as well as above 12. If your acid and antacid is combined in a single mixture, the color will depend on the ratio of acid and antacid, taking into account the strength of both the acid and the antacid. If you have significantly more antacid than acid, chances are that it will be pink (unless you're using a strong base like sodium hydroxide for your antacid, at which point it will be colorless), while if you have more acid than antacid, it'll be colorless (unless your acid is a superacid such as fluoroantimonic acid, which there's no reason why you would be using it).
What is one substance that you could use as an indicator?

What do you think will happen when an acid and metal come in contact with each other?
A chemical reaction is likley to happen
What would happen if acetic acid was mixed with hydrochloric acid?
Nothing. Two acids don't react with each other.
What might happen if you mixed a strong acid with an equally strong base?
They neutralize each other
What happen when a acid and a base react with each other?
They react and cancel each other out. The process is called neutralization and it causes them to cancel out.
What will happen in the reaction of sodium chloride powder and hydrochloric acid?
Nothing, they don't react with each other
What will happen if organic solvent mixes with an acid?
If general the two cancel each other out and you end up with salts and water.
What is an indicator and what are the common indicators used for pH?
They are molecules which change color at a certain pH. You can tell at which pH your solution is by using indicators and matching up their colors. See the Web Links to the left for some examples of indicators (there are many) and at what pH each one changes color.Application of pH indicators:Definition of Titration: Titration is a common laboratory method of quantitative/chemical analysis that can be used to determine the concentration of a known reactant.Definition of a Buffer: A mixture that is resistant to change( or in this case to pH change). These are usually made up of a weak acid and its conjugate base.Now that you know what a titration is then lets see what they are used for:* Titrations * BuffersAn indicator in a titration is used to determine the pH of the solution when the reactant and the products are at the equivalence point(when moles of H+ from acid= moles of OH- from base).
What happens when acids come in contact with each indicators?
The color of indicators is changed in acidic solutions.For example thymol blue is red at low pH.
Why do indicators change colors?
indicators change colour because of your pee.
What are facts about neutral?
Neutralization reactions happen when an acid is mixed with a base and they cancel each other out. Bases are use to treat acidic stings of wasps and hornets. Or in other words, The product of salt and water and, The Reactants are acid and base.
