Abstract: The purpose of the current study is to standardize the sodium acetate quantity for efficient heat therapy by finding the optimal solute to solvent ratio of sodium acetate and water used in the reaction solution. solute to solvent (STS) ratio is a quantity of sodium acetate to water in the solution prepared. Though the crystallization of sodium acetate phase change is commonly known as Hot ice experiment, there is no standard work for using the heat in heat therapy applications, which often lie in the usable range for superficial heat treatments because of fewer data available and works carried out. The study concentrates on deriving the optimal STS ratio for efficient heat therapy. Sodium acetate crystallization produces enough heat from 50℃ to 60℃ which lies within the human bearable range. The standardization is possible with the novel concept of Value Assessment principle and the scale narrow down approach. These two methods reduce the computation needed for standardizing the STS ratio. Values obtained using different STS ratios are represented graphically and results are interpreted from the experiment performed. The results show STS of 5.46 produces 55℃ of heat and can be used ideally for superficial heat therapy.
