The left ventricular ejection fraction (LVEF) test rate is increasingly used as a quality of care indicator for pa-. tients with heart failure. Our study produced benchmark LVEF test rates in a Medicare fee-for-service.
Toluene is a very good solvent because, unlike water, it can dissolve many organic compounds. In many commercial products, toluene is used as a solvent that is present in paint thinners, nail polish remover, glues, and correction fluid. Toluene has many uses in different industries.
Solutions in which water is the dissolving medium are called aqueous solutions. For electrolyte, water is the most important solvent. Ethanol, ammonia, and acetic acid are some of the non-aqueous solvents that are able to dissolve electrolytes.
