The pH of pure water at 50 °C is 6.55
The dissociation constant, KW, has a value of 1.0*10−14 at 25 °C, so in neutral solution both the hydrogen ion concentration and hydroxide ion concentration are 1.0*10−7 mol/L.
The pH value of pure water decreases with increasing temperatures because the dissociation constant, KW, is depending on the temperature: 7.94*10-14. So the pH of pure water at 50 °C is 6.55. At that temperature both H+ and OH- concentrations are 2.8*10-7 mol/L

Is 70 degrees Celsius in a melting or freezing point?
A temperature of 70 degrees Celsius is typically well above both the melting and freezing points of most common substances. For water, its melting point is 0 degrees Celsius and its freezing point is 0 degrees Celsius as well.
How do you make 70 degrees Fahrenheit into Celsius?
(70°F - 32) multiplied by 5/9 = 21.1°C
What liquid has a boiling point of 70 degree celsius?
An example of a liquid with a boiling point of 70 degrees Celsius is ethanol. Ethanol boils at approximately 78.37 degrees Celsius under normal atmospheric conditions.
Will 600 g of sucrose dissolve in 300 mL of water at 70 degrees celsius?
Yes, 600g of sucrose will dissolve in 300mL of water at 70 degrees Celsius because at higher temperatures, solubility of most solids in liquids generally increases. However, it's important to note that solubility can also depend on factors such as stirring, agitation, and the purity of the substances.
Is stearic acid a liquid or a solid at a room temperature of 70 degrees Celsius?
If your room temperature is 70 C then stearic acid would be in a liquid form as its melting point is 69.6 C. For the rest of us humans with a room temperature of around 24 C stearic acid is solid
What is the enthalpy change for converting 1 mol of ice at -50 degrees celsius to water at 70 degrees celsius?
The enthalpy change for converting 1 mol of ice at -50 degrees Celsius to water at 70 degrees Celsius is the sum of the enthalpy changes for the following processes: heating ice from -50 degrees Celsius to 0 degrees Celsius (heat of fusion), melting ice at 0 degrees Celsius, and heating water from 0 degrees Celsius to 70 degrees Celsius (specific heat of water).
