effect of temperature on ph
A pH of about 7 is the optimum and as the pH moves further away from the optimum pH the enzyme activity starts to slow down. Every enzyme shows highest activity at a specific temperature which is called the optimum temperature. The rate of reaction above or below this temperature is slower. Increasing the temperature causes the frequency of collisions to increase as the molecules move faster when the heat is supplied.
Summary. â¢ The pH value of a solution depends on the temperature. â¢ A pH value without a temperature value is meaningless. â¢ Solution temperature compensation converts measured pH to the pH at 25Â°C. â¢ Only pH values taken at the same temperature or converted using solution temperature compensation can be compared to each other.
