The reaction between KOH and HBr is as follows ;
KOH + HBr ---> H₂O + KBr
Stoichiometry of base to acid is 1:1 molar ratio
Both are strong acid and strong base therefore complete ionization takes place
The number of KOH moles added - 0.50 M / 1000 mL/L x 22 mL = 0.011 mol
the number of HBr moles - 0.25 M /1000 mL/L x 44 mL = 0.011 mol
the number of H⁺ ions and OH⁻ ions are equal therefore the whole amount of acid has been completely neutralised by base.
No remaining acid nor base, therefore solution is neutral.
pH = 7
thats the pH value for a neutral solution
Use the equation P=VI.
P=power (in this case 10 kilowatts or 10000 watts)
V=voltage (in this case unknown)
I=current (in this case 15.8 amps)
rewrite the equation to be V=P/I
V=(10000 watts)/(15.8 amps)
V=632.9 volts
(I think the equation requires the units for power to be watts so you need to convert kilowatts into watts)
The answer to your question is false.
This ion has 12 protons,12 neutrons and 10 electrons because the element lost 2 electrons and turned to a positive ion
An acidic solution would turn a blue litmus paper red due to the mobile and free hydrogen (H+) ions. These hydrogen ions affect the colour property of the litmus papers and thus the colour change. A litmus paper dropped into a solution of hydrogen ions turns red to indicate that the solution is acidic.
