K₂CrO₄(aq) + Ba(NO₃)₂(aq) = BaCrO₄(s) + 2KNO₃(aq)
2K⁺ + CrO₄²⁻ + Ba²⁺ + 2NO₃⁻ = BaCrO₄ + 2K⁺ + 2NO₃⁻
spectator ions: K⁺, NO₃⁻
Answer:
When barium chloride solution is mixed with copper sulphate solution and a white precipitate is observed. In double displacement reaction, a precipitate is formed which settles down at the bottom. Any reaction that produces a precipitate is called a precipitation reaction.
Answer:
A measurement is the action of measuring something, or some amount of stuff. So it is important to measure certain things right, distance, time, and accuracy are all great things to measure. Measurements can also allow us to make desicions based on the outcome of the measurement
The acids react with base and the reaction is known as neutralization
One mole of hydronium ion reacts with one mole of hydroxide ion
Here
a) HI is a monoprotic acid : one mole of HI will give one mole of hydronium ion
b) CsOH is a monohydroxide base : one mole of CsOH will give one mole of hydroxide ion
So one mole of HI will react with one mole of CsOH
The moles of CsOH taken will be calculated from molarity and volume as
Thus moles of CsOH are
moles of HI required is 0.005425 mol
volume of HI required will be
Volume of HI required is 9.86 mL
