how many ounces of a 50% acetic solution should a photographer add to 32 ounces of a 5% acetic acid solution to obtain a 10% acetic acid solution?
\n" ); document.write( "-------------------
\n" ); document.write( "Equation:
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "-------
\n" ); document.write( "0.50x + 0.05*32 = 0.10*(32+x)
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "50x + 5*32 = 10*32 + 10x
\n" ); document.write( "40x = 5*32
\n" ); document.write( "x = 4 ounces (amt. of 50% solution needed in the mixture)
\n" ); document.write( "======================================
