Al introducir un líquido puro a 20°C en una nevera, se observa que durante 10min su temperatura disminuye a razón de 2°C/min. después de este tiempo, se observa que la temperatura permanece constante durante 5 min, momento en el cual la temperatura comienza a bajar 5°C/min. Representa la curva de enfriamiento del líquido citado.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
