Answer:
4
Explanation:
bromothymol blue turns yellow betwwen then pH levels of 2 and 6
Answer:
STP stands for Standard Temperature and Pressure. NTP stands for Normal Temperature and Pressure.
Explanation:
STP is set by the IUPAC as 0°C and 100 kPa or 1 bar.
NTP is set at 101.325 kPa but uses 20°C as the temperature
Answer:
pH = 13.1
Explanation:
Hello there!
In this case, according to the given information, we can set up the following equation:

Thus, since there is 1:1 mole ratio of HCl to KOH, we can find the reacting moles as follows:

Thus, since there are less moles of HCl, we calculate the remaining moles of KOH as follows:

And the resulting concentration of KOH and OH ions as this is a strong base:
![[KOH]=[OH^-]=\frac{0.00576mol}{0.012L+0.032L}=0.131M](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5BOH%5E-%5D%3D%5Cfrac%7B0.00576mol%7D%7B0.012L%2B0.032L%7D%3D0.131M)
And the resulting pH is:

I don't see the symbols or the ions. sorry. can you type them out so I can help
Answer:
1.402 * 10^2.
Explanation:
There are 3 digits before the decimal point so the exponent is 2.
