The value for kw is 1.0 x 10-14 at 298k, but this value is temperature dependent. given what you know about kw and acid/base chemistry, what will the ph of water be at 303k if the value for kw is 1.47 x 10-14? is this solution acidic, basic, or neutral?

The pH of the water will be 6.92 and the solution will be neutral.

pH value determined how basic or acidic a solution is.

The meaning of pH is potential hydrogen.

By the formula:

Thus, the pH will be 6.92 and the solution will be neutral.

6.92; neutral

Explanation:

Kw = [H^+][OH^-] = 1.47 × 10^-14

pKw = pH + pOH = 13.83

At neutrality, [H^+] = [OH^-] and pH = pOH

2pH = 13.83

 pH =  6.92

The pH will be 6.92.

At 303 K, this will be the neutral pH, because [H^+] = [OH^-]

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

its first and third is your answer i did the qustion the fourth isnt right
