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

The pH of pure water at 70 degrees Celsius is approximately 6.14. At this temperature, the self-ionization of water is slightly altered, leading to a lower pH compared to neutral pH of 7 at room temperature.

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.
To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and then multiply by 5/9. So, for 70 degrees Fahrenheit: (70-32) x 5/9 ≈ 21 degrees 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.
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.
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
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).
