Ph value of na2co3
WebThe pH sensitivity is 58.41 mV/pH, and the pH value deviates only 0.066 from the standard pH value. The sensor is expected to be used on a large scale in the applications of wearable health ... WebUnder the conditions of both solutions, pH maintains a downward trend, but the decline rate of 1.5:1 is always lower than that of 1:1. The conclusion of this paper is that the higher the proportion of N a H C O 3: N a 2 C O 3 mixed solution, the less it has the characteristic of reducing pH value.
