indicators are chemicals that change colour in presence of an acid or an alkali. Universal indicators and pH meters are used to
measure pH. Desccribe how you would use a universal indicator to find the pH of sodium hydroxide. What colour change would you observe

Answer:
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis
have a pH greater than 7, and turn blue-purple in universal
indicator.

Explanation:
Answer:
V2 = 2.88L
Explanation:
P1= 78atm, V1= 2L, T1= 900K, P2= 45atm, V2=? T2= 750K
Applying the general gas equation
P1V1/T1 = P2V2/T2
Substitute the above
(78*2)/900= (45*V2)/750
V2= (78*2×750)/(900*45)
V2= 2.88L
