ABSTRACT:
A method for determining the freeze point of an antifreeze-containing solution which includes simply dipping into the solution to be tested a bibulous material incorporated with a pH indicator and a buffer for maintaining the pH of the absorbed solution near or within the color change range of the indicator and comparing any apparent color change developed thereon to a color chart correlated to indicate various colors corresponding to various freeze points of antifreeze-containing solutions.
