Fruit juice clean pennies best?
Lemon juice is known to clean coins well. However, if you are a coin collector, do not clean your coins. You might think this will increase the value but it actually destroy the value.Lemon juice cleans a penny fast due to its acidity. Use the link below to find out how to clean your pennies.

Which juice cleans a penny better apple or orange juice?
Generally the juice which is the most acidic would clean coins better.Lime juice is about as acidic as you'll find in a home kitchen. It has a pH of about 1.80 to 2.35 . Lemon Juice is also very acidic (2.00 to 2.60).However, there's a standard caution about trying to clean coins. If a coin has ANY collector value, home cleaning will do enough damage to the coin's surface that it will be worth less than if it had been left alone.If you have common circulation coins that are only worth face value, feel free to play around with different cleaners. But remember that if you get an old silver coin, or something like a 1909-S cent, even common household chemicals will affect the coin's surface and do a real number on its sale price.

Where can a recipe for lemon bars be found that uses lemon extract instead of lemon juice?
I cannot find any such recipe. Lemon extract actually comes from the lemon peel, not the juice of the lemon.

Try camomile, or lemon juice!
What is the purpose of semi logarithm?
The y-axis on a semi logarithmic chart is exponential. This way, when an exponential function is depicted in the chart, it will evolve as a linear function. You often do this to proove that the function is exponential and/or as a tool to help you find the equation for the function. For more see: http://www.answers.com/topic/semi-logarithmic-plot
How do you find the horizontal asymptote of a logarithmic function where x equals 7.5 and y equals 50?
One point on a logarithmic graph is not sufficient to determine its parameters. It is, therefore, impossible to answer the question.
Why sour liquid can clean things?
I think you might find it to be..Lemon juice..
What can you substitute for lemon juice in a receipe?
Lemon Grass if you can find it... You can use real lemon, real lime or bottled lime juice and sometimes pineapple juice will work depending on what you are making. Marcy lime , pineapple and orane hice will all work as long as it is acidid
Which juice cleans pennies the best lemon grape or orange?
Lemon juice. It has a pH of 2.3, whereas orange juice has a pH of 3.3. What is being cleaned off is the CuO and CuCO3 that forms on the penny. Both O2- and CO32- are bases, so the stronger the acid, the more effectively they will be reacted away. I did a quick online search for the pH of grape juice but did not find anything, but given that it lacks the sour taste that orange and lemon juice have (an indicator of acidity), I would have to assume that it is not as acidic as either lemon or orange juice.
What is the hydronium ion concentration in lemon juice that has a pH of 2.25?
The pH of vinegar is around 3.4. The pH of lemon juice is around 2.3. Since pH = -log(conc. H+ ions), we simply need to solve for the conc. of H+ ions in both substances and find the difference. There are approximately 4.6 x 10^-3 M hydronium ions in lemon juice than vinegar.
What solution you can find at home?
Example: mouthwash, beer, wine, vinegar, lemon juice, cleaning agents etc.
How do you find the vertical asymptote for the logarithmic function f of x equals log x?
The only way I ever learned to find it was to think about it. The function f(x) = log(x) only exists of 'x' is positive. As 'x' gets smaller and smaller, the function asymptotically approaches the y-axis.
How do you use inverse log on graphing calculator?
The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
Can you substitute lime juice for lemon juice in canning?
You may, but you may not like the end product. The lemon juice adds acidity like orange juice will that help to prevent spoilage, but lemon juice also contributes to the taste. Orange juice will too, but you may find it much sweeter.
